Silvian Gates

At the end of the 18th century, a stone wall was being constructed in Gatchina to enclose the Sylvia Park. The contractor — Plastinin — built the gates at the site of the main entrance to the new park according to the design of architect Brenna between 1792 and 1794. (Some sources mention a different builder — the "master of stonework" Visconti — and different construction dates — 1794–1797.)

The gates, named the "Sylvian Gates," are made of Pudost stone, feature a triangular pediment and an arch, on the keystone of which a mask of a bearded "forest god" is carved on both sides. On the outer side of the gates, in the center of the tympanum, there is a metal plate with the inscription "Silvia." The gate leaves are made of metal lattice.

During their existence, the Sylvian Gates have remained practically undamaged and are in satisfactory condition. Near the gates are the guardhouse building and the Monument to the Komsomol Heroes.
