In 1782, according to the design of architect Charles Cameron, an Obelisk was erected in memory of the founding of Pavlovsk (on the shore of the Mariental Pond). On the cast-iron plaque is inscribed: "Pavlovsk began to be built in 1777" — the date when Catherine II gifted the lands of future Pavlovsk to Paul Petrovich in honor of the birth on December 12, 1777, of his son Alexander I. The heir to the throne Paul Petrovich and Grand Duchess Maria Feodorovna received from Empress Catherine II a gift of 362 desyatinas of land on the banks of the Slavyanka River, along with the villages of Linna, located in the area of today's Five Corners, and Kuznetsy, which was on the territory of the House of Youth Creativity, for the arrangement of a Summer residence. As the archival "Estimate by account" testifies, on the same day the construction of "His Highness's House" began. This date is considered the birthday of Pavlovsk.

The landscape area where the obelisk stands is called the Swiss Hills (Heights). From the Bip fortress to the obelisk marking the founding of Pavlovsk ran an alley.

In 1778, starting in spring, work began on arranging the residence of the heir to the throne's family. Peasants and soldiers from garrison regiments, gathered from villages, built two wooden two-story houses on the elevated banks of the Slavyanka: "Her Majesty's little house," called "Paullust" (on the site of the left wing of the current palace), and "His Majesty's little house," named after Maria Feodorovna "Mariental" (at the confluence of the Slavyanka and Tyzva rivers). The owners named their new estate "the village of Pavlovsk."

On November 12, 1796, a week after ascending the throne, Emperor Paul I issued a decree renaming the village into a town. At the same time, the settlements of Tyarlevo, Lipitsy, Fedorovsky Posad, Krasnoye Selo with peasants and lands were annexed to Pavlovsk.
