Annenhof maison, royal palace from the 18th century in Saint Petersburg, Russia

Annenhof Palace is an 18th-century royal residence located on the Neva River near Ekateringof in Saint Petersburg, featuring a single main story with a mezzanine level. Two pavilions flank the central building and are connected through a gated entrance, creating a unified architectural composition typical of the period.

Peter the Great commissioned the palace in 1714 as a residence for his eldest daughter Anna Petrovna, with construction extending through the early 1730s. The building emerged during a period of rapid palace development as Saint Petersburg established itself as Russia's capital.

During Catherine II's reign in 1764, Italian impresario Giovanni Battista Locatelli leased the palace to organize masquerade balls and opera performances.

The palace sits on the Neva riverbank near Ekateringof, making it easy for visitors to locate as part of exploring historical Saint Petersburg architecture. The riverside location provides natural orientation points when visiting nearby palaces and other historical sites.

The palace measurements were precisely calculated at 25.56 meters in length and 12.78 meters in width, following the Russian sazhen measurement system.
