The Princes' Islands - the main prison of the Byzantine Empire, the island of Proti

Kınalıada, Akgünlük St. No:13, 34977 Adalar/Istanbul, Turkey

The closest island to Istanbul is Kınalıada, also known as Henna Island, historically known as Proti, meaning the first island to New Rome. On this small island, covering just over one square kilometer, there were at least three monasteries, one of which held Emperor Michael I Rangabe in captivity. In response to the betrayal by his general Leo the Armenian in 813, he decided to become a monk and go into voluntary exile on Proti, where he peacefully died in 844.
The magnificence of nature and the countless coups d'état that abound in the history of the Eastern Roman Empire, as a result of which deposed emperors and empresses, the elite of Byzantine nobility, and deposed patriarchs were forced to spend their days in exile on small patches of land in the Sea of Marmara, created a loud fame for the Princes' Islands and made them famous not only to contemporaries of historical figures but also to modern travelers who take a ferry to relax on the beaches of these fairy-tale islands.
The islands are located in the Sea of Marmara near Constantinople and are historically known as the Princes' Islands, the Red Islands, or in the modern Turkish version - Adalar (Kızıl-Adalar - "red islands"). In ancient times, the islands were called the Demonisians, named after the owner of a copper mine. There are nine islands in total. Currently, only four of them are open to visitors. The others are uninhabited or privately owned.
First of all, it should be noted that there were never prisons as such on the Princes' Islands, but their functions were successfully performed by monasteries, of which there were many on each tiny island. Despite the seeming proximity to the mainland shore, it was difficult for prisoners to escape due to constant winds and strong currents.
Researchers find it difficult to precisely identify the originator of the idea to exile unwanted high-status persons here, but it is assumed that one of the first was the founder of New Rome, Constantine the Great, who, based on a false accusation by his new wife, ordered the execution of his son and Rome’s favorite, Crispus. Crispus was renowned as a talented general and was designated as heir to the throne, but he became unwelcome to his stepmother, who secured his exile to Thrace, where the father's order was carried out. Constantine did not wish to change the death sentence to life imprisonment, and when the details of the crime emerged, the people of Rome began to riot and refused to obey the emperor. Constantine’s mother conducted her own investigation and exposed his wife, who was forced to confess to her slander against Crispus. But it was already too late, and Constantine’s life was under threat, which finally pushed him to hasten the transfer of the empire’s capital to New Rome and simultaneously decide to find a place for exile near the new capital so that in the event of another miscarriage of justice, the innocently condemned could be returned to society.
The closest island to Istanbul is Kınalıada (Kınalıada) or Henna Island, better known in history as Proti, meaning the first island to New Rome. On this small island of just over one square kilometer, there were at least three monasteries, one of which held Emperor Michael I Rangabe in captivity. In response to the betrayal of his commander Leo the Armenian in 813, he decided to become a monk and voluntarily exile himself to Proti, where he peacefully died in 844.
Around the same time, the failed claimant to power Vardan Turk, wishing to avoid punishment, voluntarily took monastic vows and, with the emperor’s consent, retired to Proti.
 "In the month of July, on the 19th day; on the fourth day of the week, at the first hour, Vardanes the patrician and eastern commander, nicknamed Turk, was proclaimed emperor by foreign legions; although he refused for a long time, he could not avoid them, came to Chrysopolis and, having stayed around it for 8 days, was not accepted by the city’s inhabitants and returned to Malagina. But, fearing God and taking it to heart that no Christian blood should be shed for him, he wrote to Nikephoros and, having received from him a written honorable word personally signed, to which the most holy Patriarch Tarasius and all patricians subscribed, that he would be kept safe without harm or punishment, as well as all who supported him, on the 8th of September, at midnight, he secretly left the army, arrived at Kii of Bithynia, to the monastery of Heraclius, and, finding there a boat sent by the emperor, immediately tonsured, donned monastic robes, and sailed to the island called Proti, where he founded a monastery, hoping that the fierce Nikephoros would respect the terrible word given and would not harm him in any way."
On December 17, 944, Emperor Romanos Lekapenos, deposed by his own sons, was brought to the island of Proti. And just a few days later, on December 27, Romanos’ sons, themselves victims of a conspiracy and palace coup, were in turn deposed by Constantine VII Porphyrogennetos and followed their father. The dramatic scene was described by contemporary Liutprand: "When Romanos, their father, heard that they had arrived, he went out beyond the monastery gates to meet them and with a joyful face said: 'What joy,' he said, 'that your majesties have decided to visit our insignificance here. I suppose it was filial love that drove me from the palace that did not allow you to stay there long. How good it is that you sent me ahead. For the brothers would not have known how to receive emperors if they did not have me, long experienced in imperial ceremonies. The broth is already boiling, sweet beans and young garlic.' While Romanos mocked them, Stephen and Constantine stood ashamed, eyes cast to the ground."
As can be seen from these descriptions, Romanos and other failed emperors were sent to the Princes' Islands to a monastery. No strict imprisonment was apparently intended here. Romanos lived with the brethren, worked alongside the monks, and ate with them. Visits were apparently allowed, communication permitted, so the former emperor was not to spend the rest of his life in complete solitude and loneliness, and certainly was not subjected to any physical violence.
At the top of the island there was previously a monastery built by order of Romanos IV Diogenes - one of the best rulers of Byzantium. But later, the patron of the construction was also exiled here as a result of the intrigue of his own brother Constantine X - John Doukas, who managed through intrigues to depose Romanos IV and place his nephew Michael VII on the throne. 
In 1072, the deposed and blinded Emperor Romanos VI Diogenes ended his days in torment on the island of Proti. This was perhaps the last major and so dramatic event associated with the Princes' Islands. Defeated in several battles and abandoned by those he trusted, Romanos surrendered under a guarantee of personal safety. But on the way to the capital, still in Asia Minor, Diogenes was blinded, crushed with a shield in some closet. Romanos vainly recalled the promises made to him. For lack of an executioner and tools, the execution was carried out by some random man with a thick tent pole. Four times the heated iron was plunged into the unfortunate emperor’s eye sockets. Romanos himself, screaming, convinced his tormentors that his eyes had flowed out. Diogenes’ face swelled grotesquely (apparently sepsis began), and a few days later (August 4, 1072) he died.
In 969, the famous Theophano was also exiled to the island of Proti. She had killed her husband Emperor Nikephoros Phokas in December 969 and placed John Tzimiskes on the throne. She managed to return to Constantinople, where she tried to find refuge in the Hagia Sophia church. However, John Tzimiskes remained adamant. He sent his loyal eunuch Basil Noph to Hagia Sophia, indifferent to female charms, who "dragged her out, during which she fiercely cursed the emperor and Basil, calling him a Scythian and barbarian, and struck him on the cheeks with her fists." Based on these scant details, it can be concluded that Theophano was apparently not held under strict guard, as she was able to prepare an escape and organize her return to the capital, although natural barriers (monastic walls and the sea) should have kept her at a safe distance from the capital.

JFPQ+CC Mont-Saint-Michel, France

Mont Saint-Michel (Mont Saint-Michel — the mountain of Archangel Michael) is a rocky island, a fortress island, located on the northwest coast of France, in Normandy, Manche department. On the island stands a formidable granite rock, and on the rock — a majestic monastery with a Gothic church soaring into the sky. Around the island — not water, but sandy dunes, yet every day from the abbey walls one can observe the entire landscape transform — as the tide comes in. Up until the French Revolution, the political prisoners held in the abbey’s metal cages and dungeons were mostly pamphleteers and Jansenists. Having a dubious reputation as a place from which there is no escape, the prison at Mont Saint-Michel became popularly known as the "Sea Bastille."

Norfolk was an English penal colony where the most dangerous criminals were sent from England and Australia. In 1814, the colony was abandoned as it was too costly, but in 1825 the prison was reinstated, and dangerous criminals—both common and political—began to be imprisoned there. Even minor offenses from England could lead to transportation. For thirty years, Norfolk served as a penal prison with a strict regime. The penal colony on the island was finally closed in 1854, but the prison buildings are still carefully preserved on the island and have become a tourist attraction.

Saint Helena Island – From Napoleon to the Present Day

27MR+XCW, STHL 1ZZ, St. Helena Island

The fate of Saint Helena Island as a prison island was decided when the Portuguese nobleman Fernando Lopes became a voluntary exile there in 1515. Geographically, the island is perfectly suited for use as a prison. The sheer cliffs surrounding the interior make Saint Helena Island an almost impregnable fortress. The first mention of a prison being built on the island appears in the island’s records from 1683. Saint Helena Island was once used by Britain as a prison for such notable figures as Emperor Napoleon, Prince Dinizulu, and the Sultan of Zanzibar. The island was also used to house nearly 5,000 Boer prisoners of war.

Princes' Islands - the main prison of the Byzantine Empire, Büyükada Island (Prinkipo or Prinkipos)

Çınar Square No. 3 Büyükada, Büyükada-Nizam, 34970 Adalar/Istanbul, Turkey

The largest island of the Büyükada archipelago (Prinkipo or Prinkipos), where most travelers staying in Istanbul go for vacation. It is notable for its high and steep shores, dense forest, and ancient monasteries. The first records of influential figures of the Byzantine Empire exiled here date back to the 6th century, when by order of Justinian I the Great in 565, the Patriarch of Constantinople, Eutychius, was exiled to the island for his teaching on the incorruptibility of the flesh of Jesus Christ. It was this island that gave its name to the entire archipelago – the Prinkipo Islands, which in Russian came to be called the Princes' Islands. No "princes" were ever exiled here. The island has many beautiful wooden mansions.

Princes' Islands - the main prison of the Byzantine Empire, Sedef Island

Büyükada - Maden Neighborhood, Füsun Street No:30, 34970 Adalar/Istanbul, Turkey

The outermost of the Princes' Islands, Sedef Island (Mother-of-Pearl Island), Terevintos or Terevinf, is located east of Büyükada Island (Prinkipo). Originally, the island was called Terebint (Anderovitos) due to the turpentine trees of the pistachio genus growing there, which is why Russian travelers referred to this island as Pistachio Island. A beautiful Turkish legend says that these trees were brought to the island by the son-in-law of Sultan Abdülmecid, but in reality, this was done by ancient Greek settlers. Currently, the island is privately owned and can be admired from the shore of Prinkipo, as the islet is only about 250-300 meters away. Historians, however, call this patch of land the Island of the Two Patriarchs.

Princes' Islands - the main prison of the Byzantine Empire, island Yassıada

VX7V+P6, 34970 Princes' Islands/Istanbul, Turkey

This is the official name of the island Yassıada (Flat Island) since 2013 - the Island of Democracy and Freedom. Originally it was called Plati (Platos - "flat"). The most mysterious of all the islands due to the abundance of ruins of ancient temples and churches. Part of the underground chambers, which were used as dungeons, warehouses, and cisterns, still remain on the island to this day. It was from here that the practice of exiling particularly important figures of the empire began. Thus, one of the first prisoners of the island (in the second half of the 4th century) was one of the founders of the Armenian Orthodox Church, Patriarch Nerses I the Great, who was exiled to the island by the Roman Emperor Valens because the patriarch condemned him for his adherence to Arianism.

Princes' Islands - the main prison of the Byzantine Empire, the island of Oksia

VXGF+92 Princes' Islands/Istanbul, Turkey

No one tried to escape from this island; on the contrary, people sought by all means to reach it and seek unity with God. During Byzantine times, a house for orphans, the Church of Archangel Michael, and a monastery were built on the small island, from the walls of which several patriarchs emerged. The Patriarch of Constantinople, Michael II Kourkouas, voluntarily went into exile on the island after realizing in 1146 that he was not suited to manage the church affairs of the empire, earning the respect of his contemporaries for this. In 1073, John Doukas, brother of Emperor Constantine X, fled to the island, fearing retribution from Nikephoritzes—the regent of Michael VIII. However, Nikephoritzes himself soon fell into disgrace and was also sent to Oxeia in 1078, where he died from torture.

In past years, it was mainly intended for holding members of the mafia and the “Red Brigades” terrorists, and housed people such as mafia boss Toto Riina.

Longholmen Hostel, the former Central Prison of Sweden on the eponymous island

Långholmsmuren 20, 117 33 Stockholm, Sweden

Longholmen Prison, officially the Central Prison of Longholmen (Långholmens centralfängelse), was historically one of the largest prison institutions in Sweden with more than 500 cells, located on the island of Longholmen in Stockholm. It was built between 1874 and 1880 as Sweden's central prison and was temporarily closed from 1972 to 1975.

Fort Porokhovoy or the Gunpowder Cellar of the Naval Department

XRQ7+R9 Kronstadt District, Saint Petersburg, Russia

In Kronstadt, there used to be many powder magazines in ancient times. Both on the island itself, at the forts of the Kronstadt fortress, and on the ships. Throughout Kronstadt’s history, gunpowder explosions happened frequently: due to lightning, careless handling, and as a result of sabotage. Therefore, when they began building the Northern numbered forts, it was decided to construct a powder magazine close to the forts but still far from the city. The entire architecture of the fort fully met the requirements for the safe storage of gunpowder and ammunition: island location, a powerful foundation made of granite blocks, two-meter-thick brick walls, and the most advanced heating and ventilation system of that time. Inside, the “Powder Magazine” is a two-level warehouse, with rooms connected by galleries; on the floor, you can still see the remains of rails along which small wagons were moved—this allowed for the rapid transportation of ammunition within the fort.
