The Dolgorukov-Oldenburg House was built in 1831-1832 by S. Shustov for Prince Dolgorukov. It is a small wooden building by the very bank of the river, cubic in shape, crowned by a low cupola and adorned by Doric six-columned porticoes supporting three balconies. Originally belonging to Prince Dolgorukov, it passed on to the Prince of Oldenburg, a nephew of Nicholas I, which is why it is often called the Dolgorukov-Oldenburg Villa. The house is one of the few surviving examples of Russian wooden architecture in the age of Classicism. Later, the view of the house has been improved by the construction of a granite ramp leading down to the river with the cast-iron sphinxes set on either side.
