These mansions, now commonly referred to as the Red Chamber, were built in the 70s and 80s of the 17th century. Tsars Fyodor Alekseevich and Peter I, as well as Empress Catherine II, probably stayed here. The mansions are distinguished by picturesque combinations of volumes, each of which is completed with a special steep roof. Rich window trim and a magnificent front porch topped with two tents add even more expressiveness to the building.
