At 10 Kolpachny Lane in Moscow stands an ancient building known as the Chambers of Ivan Mazepa. However, the hetman did not live here; his house was nearby, and only the walls remain. The name 'Mazepa's Chambers' was coined by Soviet architects who, in the mid-20th century, claimed that a historical figure lived here to obtain permission for reconstruction.

And although they were mistaken about the name, a historical figure did indeed reside in this house. It was Abram Lopukhin, the brother of Peter I's first wife. He supported Tsarevich Alexei and participated in a conspiracy against Peter the Great, for which he was executed, and his head was displayed in the square in St. Petersburg.

The house was well-equipped for its time, featuring a unique heating system. Warm air from the stoves circulated through the rooms via wall pipes and vents, so Lopukhin did not freeze. He did not live alone; the first floor was occupied by servants. Lopukhin ascended to his quarters via a two-tiered staircase and accessed his rooms by walking around the house through an external gallery to avoid passing through the servants' quarters.

The house was built with care and remained residential for almost 250 years. During the Soviet era, it housed communal apartments until the 1960s. Then, for a time, the building housed the OVIR, and after restoration, it regained its original appearance. Today, it contains office spaces.
