The administrative buildings are a complex of administrative structures built in the early 19th century in the Kaluga province. This architectural ensemble is located in Kaluga on the left bank of the Oka River and is a cultural heritage site of Russia, protected by the state.

The complex consists of a U-shaped group of buildings connected by passage arches, surrounding the Central City Park of Culture and Recreation with the Trinity Cathedral.

The construction of Kaluga according to the master plan developed under the first Kaluga governor M. N. Krechetnikov began with the administrative buildings on the site where the wooden Kaluga Kremlin once stood. These buildings were designed by provincial architect P. R. Nikitin as the future center of the city, uniting all administrative bodies of the province. The construction, costing over 200 thousand rubles, began in 1780 and was completed in 1809 under Governor A. L. Lvov, supervised by architect I. D. Yasnigin.

The administrative buildings are mentioned in the description of the Kaluga governorate from 1785:

The stone building, located parallel to the Oka, has two floors, a length of 64 fathoms, and a width of 6 fathoms. It houses the Governor's Office, the Public Charity Office, the Consistory Court, a hall for the General Assembly, the Drawing Office, and the City Administration. On both sides of this building, there are two two-story wings, each 103 fathoms long, connected to the main building by stone galleries each 20 fathoms long.

During the war with Napoleon, one of the wings housed a military hospital. Today, the administrative buildings are used by various institutions:

The western wing hosts the Kaluga branch of the Moscow State Technical University named after N. E. Bauman.

The eastern wing houses the Kaluga Spiritual Seminary and the residence of the Kaluga and Borovsk Metropolitan.
