Between the Grand Palace and the Bread House, also known as the Kitchen Block, there is a gallery built in 1784-1785 according to the design of V. I. Bazhenov. It connected the Bread House with the palace of 'Their Imperial Highnesses', which was dismantled by order of Catherine II, and in its place, the Grand Palace was constructed. The gallery also separated the estate courtyard from the park.

The gallery served an exclusively decorative function, creating the impression of a unified ensemble of the Grand Palace and the Bread House. Such galleries were characteristic of palace and estate architecture of the late 18th century.

The structure of the gallery consists of two closely positioned walls without a roof. Between them runs a corridor, bounded at the ends by the walls of the buildings, and closer to the middle, by the gate supports.

By the end of the 19th century, the gallery was severely damaged, and by the mid-20th century, it was in a ruined state, having lost a significant part of its structural and decorative elements.

Restoration of the gallery was carried out in 1986-1987. In 2005, during archaeological research, white stone foundations of the eastern part of the fence were discovered.
