The gates of Peter III's toy fortress in Oranienbaum are a vivid example of small-scale architecture. They served as the entrance to a small training ground created for teaching the young heir to the throne military skills in conditions that simulated fortification structures. The complex covered an area of 2 hectares.

The architectural project of the gates was developed by Antonio Rinaldi. The Italian architect designed them in a style that combines elements of Rococo and early Classicism. Above the gates rises an octagonal turret with a weather vane, which indicates the start date of construction, 1757. This structure was intended as an observation point for surveying the surroundings and anticipating the approach of a hypothetical enemy.

Historical documents attest to 17 wooden and stone buildings on the territory of the Peterstadt fortress, including soldiers' barracks, the Commandant's House, an arsenal, and a garrison church. To this day, only the Honorary Gates and the miniature palace of Peter III have survived. In the 1920s, the gates, like the entire palace complex, were looted and stripped of their rich decor made of gilded copper.

Restoration of the gates began in 1952. In the 1960s, their appearance was recreated based on historical drawings, and some decorative elements were partially restored. However, the gates' leaves, a unique work of art from the Elizabethan era, are still under restoration and have not been returned to their place.
