Vadstena Castle

Vadstena Castle, constructed in 1545 by King Gustav I, was initially built as a fortress to protect Stockholm, the capital city of Sweden at the time. After more than a century of construction, all kings of the House of Vasa had contributed to the castle by 1620. Initially designed as a defensive structure, it was later transformed into a habitable castle in the 1550s. Vadstena Castle was a royal palace until 1716, after which it became a storage barn for grain. Since 1899, the castle houses the Provincial Archives and a Castle Museum with 16th and 17th century furniture, portraits, and paintings. Today, visitors can also find the International Vadstena Academy, Sweden's smallest opera house, commissioning new operas and reviving lost operas from archival scores. During summers, the courtyard of the castle hosts many concerts, both classical and pop music.
