It preserves the history of both the Catherine Cathedral and Tsarskoye Selo as a whole.

A unique model of Tsarskoye Selo with buildings from the late XIX - early XX centuries was installed according to the drawings of the architect Alexei Mikhalychev.

While in a cozy room, you can walk around the entire city in 20 minutes, listening to its colorful history and the life of the monarchs of the House of Romanov; see carefully preserved exhibits of this Cathedral before its explosion: the crucifixion of Jesus Christ, the decoration of the five-tiered iconostasis, as well as objects found during archaeological excavations before the reconstruction of the Cathedral.

Models of temples and churches of the Tsarskoye Selo deanery remind us of the history of both recreated and unpreserved historical buildings.

Exhibitions are held in a separate space. The museum has a cozy refectory. Guests like to visit it after the excursion.
