Priory Park

Priory Palace is an original palace in Gatchina (Гатчина), Russia. It was built in 1799 by the architect N. A. Lvov on the shore of the Black Lake (Chyornoye ozero / Чёрное озеро). Constructed for the Russian Grand Priory of the Order of St John, it was presented to the Order by a decree of Paul I of Russia dated August 23, 1799.

Connetable (Russian: Коннетабль) — obelisk and square in Gatchina, placed on the cross of 25 October prospect (main city's street) and Krasnoarmeysky prospect. Probably the author of the project was Vincenzo Brenna.
