Sylvia park, Historic park in Gatchina, Russia.

Sylvia Park is a regular park of about 17.5 hectares in Gatchina, laid out from 1792 to 1800 by architect Vincenzo Brenna and gardener John Hackett. It lies on the left bank of the Palace Park, northwest of the Great Gatchina Palace, and is bounded by Krasnoarmeysky Prospekt. A stone wall with the Sylvia Gates separates it from the Palace Park, and the Kolpanka River divides it from the Zverinets park.

The park was founded in the late 1700s as part of a large estate and was meant to reorganize the forests and open land. A foreign-trained gardener brought the plans to life.

The park has long served as a place where visitors walk and enjoy nature around the palaces nearby. It shows how estate owners shaped their lands as private retreat spaces for themselves.

The park lies northwest of the Great Gatchina Palace, on the left bank of the Kolpanka, with its city edge along Krasnoarmeysky Prospekt. Entrances are through the Silvia, Cascade and Black gates, the last now ruined; guardhouses stand by the Silvia and Cascade gates. A metal fence has enclosed the grounds since 2012, and some inner paths along the brick wall are overgrown.

The park shows an early form of landscape design where artificial ponds and hills were placed to create specific views and feelings. This approach was groundbreaking for garden art in Russia.
