Priory Palace
A palace built of earth for the Order of St John.
Priory Palace, known in Russian as Приоратский дворец, sits on the shore of Black Lake in Gatchina, a suburb of Saint Petersburg in northwest Russia. Architect Nikolay Lvov designed and built the structure in 1799 for the Russian Grand Priory of the Order of St John. Tsar Paul I officially granted the palace to the Order by decree on August 23 of that same year.
The palace is the only surviving building in Russia constructed largely through earthwork techniques. Its walls, fence, and courtyard structures were made by layering compacted loam and pouring lime mortar between the layers. A retaining wall, however, uses Pudost stone—a material common to many buildings in Gatchina. Researchers highlight the palace’s precise layout, original composition, and deliberate avoidance of symmetry.

Lore & Background
Priory Palace was constructed in 1799 on the shore of the Black Lake in Gatchina, a suburb of Saint Petersburg. The architect Nikolay Lvov designed the palace for the Russian Grand Priory of the Order of St John, and it was formally presented to the Order by a decree of Emperor Paul I on August 23, 1799. The palace is unique in Russia for its primary construction method: layers of compacted loam poured with lime mortar, a technique known as earthwork or rammed earth. This method was used not only for the palace walls but also for the fence and court buildings.
Reader's Guide
Priory Palace stands as a singular architectural monument in Russia, being the only surviving structure built predominantly with rammed earth technology. Its construction in 1799 for the Russian Grand Priory of the Order of St John reflects a specific historical moment under Paul I, who granted the palace to the Order. The use of Pudost stone for the retaining wall connects it to other Gatchina buildings. Researchers note the precision of its layout, original composition, and characteristic refusal of symmetry, marking it as an innovative design of its time. Today, it remains a preserved example of earthwork construction and a link to the Order of St John's presence in Russia.
