Building The Teatro Emperador is a building included in the catalog of protected assets and elements of the special plan for the urban ensemble of the city of León (PECU). Its degree of protection is therefore level 2, which corresponds to a comprehensive type of protection, justifying it in the way the building has to solve an important crossroads in the widening of León. The built complex is resolved with a main volume housing the theater and cinematograph, a set of premises on the first floor where different stores are located and several outbuildings in height where there are various uses of offices, hostel and housing. The building has five floors, basement, ground floor and three more, although it rises to one more at the top as a tower on the chamfered corner with Independencia and Santa Nonia. Interior layout The floor plan of the building contrasts the horseshoe shape of the hall, inserted in the center, with the polygonal perimeter of the building as a whole, which is trapezoidal in shape. This contrast is resolved by occupying the open space with tertiary or residential uses, such as offices or housing. The development of the plot seeks to resolve in a monumental way a landmark of the city's expansion. Because of its multipurpose nature, the organization of the hall is conditioned by the almost impossible compromise between the requirements of the theater, which advise a focal arrangement of the stalls versus the parallelism of the seats with the screen, inherent to the projection of cinema. In this dilemma, the architects opted for the dramatic function by adopting the typical theatrical horseshoe shape, although they tried to correct the disadvantages for the cinematic spectacle by aligning the rows of seats on the mezzanine and the amphitheater. Paradoxically, the stage is tiny, only 13 meters wide and 10 meters deep, with a reduced free height; in short, an insufficient stage for any kind of performance. The main hall is organized in
