The Church of St. Nicholas is an Eastern Orthodox Church in the Bulgarian capital of Sofia. The church was built in the 13th century by Kaloyan the sebastocrator as a small family church on today's Kaloyan Street behind the Rila Hotel. It is assumed that the church was erected on the site of the surviving parts of the palace complex that had once stood there which was built during the Roman Empire and accommodated Constantine the Great. Today these parts are preserved and can be seen in the authentic underground walls of the temple.

The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
