Orlov-Denisov manor park, Federal cultural heritage site with artificial pond in Saint Petersburg, Russia.

Orlov-Denisov manor park is a federal cultural heritage site in the Kolomyagi historical district of Saint Petersburg, centred on the Grafsky Pond, an artificial body of water. Glavnaya Street runs along its northwest side and Beryozovaya Street along the southeast, while the Nikitinsky bridge-dam crosses the southern end, carrying 1st Nikitinskaya Street.

The pond lies in the park of the Orlov-Denisov estate in Kolomyagi, a historical district of Saint Petersburg. The estate on its shore belonged to Count Orlov-Denisov, whose name the park carries. The pond itself sits on city land and, unlike the park and manor, is not owned by a subsidiary of the SU-155 holding. Sergei Glezerov's book Kolomyagi covers the district's history.

The park reflects how Saint Petersburg's noble families shaped their country estates in the 1800s as private retreats. Walking through it today, you notice how the layout and plantings still show what mattered to those who lived here.

The grounds are accessible on foot with multiple walking routes available for exploring at your own pace. Wear sturdy shoes, as some paths can become muddy depending on the season and recent weather.

The pond itself belongs to the city, while the park and the manor are held by a subsidiary of the SU-155 holding company — an unusual split of ownership for a single estate. The Nikitinsky bridge-dam at the southern tip carries 1st Nikitinskaya Street across the water.
