Middle Tsaritsyno Palace, Palace in Orekhovo-Borisovo Severnoye District, Russia.

Middle Tsaritsyno Palace, also called the Opera House, is a two-storey palace built by Vasily Bazhenov in 1776–1778. Its ground floor has tall pointed arches and pilaster-like projections with white-stone inserts; the upper floor, separated by a white-stone cornice, has Italianate windows and obelisk-like decoration. A parapet over two metres high carries white-stone double-headed eagles on the south and north facades.

Architect Vasily Bazhenov began construction in 1776 as part of Catherine II's plan to establish a grand imperial residence in southern Moscow. The project expressed an ambitious vision for a new center of power outside the city center.

The palace serves as an exhibition space within the Tsaritsyno Museum complex, displaying collections of decorative arts and artifacts from the imperial Russian period. Visitors can see how the rooms are arranged to showcase historical objects and what artistic works from that era are preserved here.

The palace is accessible via Tsaritsyno or Orekhovo metro stations on Line 2, with guided tours available in multiple languages. It is helpful to check current opening hours and tour programs before visiting to make the most of your visit.

The building incorporates mathematical patterns and symmetrical designs that some researchers interpret as references to Masonic symbolism in architecture. These hidden layers of meaning make the palace an intriguing subject for visitors interested in the history of symbolism.
