The walls were constructed using 'pisé' or rammed-earth technology, a rare technique for 18th-century royal residential buildings.
The palace was specifically commissioned for the Grand Prior of the Order of Malta after Emperor Paul I became the Order's protector.
During the late 19th century, the building served as a summer residence for the imperial family's singers and choir members.
The building was designed to be fireproof due to the earth-based construction, a significant safety consideration at the time.
It is the only building in Russia constructed of earth that has remained intact and functional for over two centuries.
The tower's spire is constructed from wood, contrasting with the solid mass of the earth walls below.
During the Soviet period, the palace served various roles, including a pioneer camp and a recreational facility.
The structure relies on the Gatchina park’s unique lake system for its serene, reflective aesthetic.
The interior architectural details were designed to mimic the ascetic, austere style of the Maltese Order.
The Prioratsky Palace is a unique earth-walled structure commissioned by Emperor Paul I for the Prior of the Order of St. John of Jerusalem. Built in 1799 by architect Nikolay Lvov, it serves as the only surviving example of rammed-earth construction technique in Russia. The building is situated on the shore of Black Lake in Gatchina, integrated into the historical landscape of the Gatchina park ensemble. Unlike traditional stone palaces, its exterior walls are composed of compressed soil mixed with lime and clay, reinforced with wooden frames. The interior layout is compact, reflecting its original purpose as a residence for the Prior of the Maltese Order. The palace features a distinct Gothic-inspired style with a prominent spire and pointed arches. It survived the bombings of World War II with significant structural damage and has since undergone extensive restoration. Today, it functions as a museum showcasing the history of the Order of St. John in Russia and the palace's specific architectural methodology.
The opposite bank of Black Lake provides the best vantage point to capture the full palace facade and its reflection in the water.
Combine your visit with a walk through the surrounding Gatchina Park for a complete experience of the area's landscape design.
Look for the display samples explaining the rammed-earth construction process inside the museum.
Wear comfortable walking shoes, as the paths around the lake are unpaved and can be uneven.
Do not attempt to walk on the exterior earth walls or climb the steep embankment directly adjacent to the structure.
Closed on Mondays and the first Monday of every month for maintenance.
Maintain a quiet volume and avoid touching the historical wall surfaces, as the rammed-earth composition is sensitive.
