The Odessa Opera House is known, first of all, for its architecture, and its layout and technical data are not inferior to the best in Europe.
In plan, the building consists of a horseshoe-shaped audience hall surrounded by galleries, a foyer and a rectangular stage with utility rooms. Along the longitudinal axis of the building there is a two-story main entrance portal with a high attic, and along the transverse axis there are three-arched galleries of the side entrances. The planning is radial - from the center, passages are laid out along the radii in different directions to the exit. The stairs leading directly to the theater exit also have tiers. The building is covered with a system of metal trusses, zinc coating. The covering of the audience hall resembles the surface of a part of an ellipsoid, cut off by planes along the horizontal and vertical axes of symmetry, it is crowned with a round lantern with a dome, completed by a low spire.
