The place where the Yusupov garden is now located was located between the Fontanka and Sadovaya. The area of this site was 9 hectares. Peter I granted it to Prince GD. Yusupov. Some time later, a French garden with flower beds, canals and ponds was broken on this site. Through the park there was an alley that led to the Fontanka River. The project of a house, a one-story wooden mansion on a stone foundation, built here in 1730, was designed and implemented by Domenico Trezzini, an Italian architect and engineer.
