Moscow Manege is a large oblong building which gives its name to the vast Manege Square, which was cleared in the 1930s, adjacent to the more famous Red Square. A manège is an indoor riding academy. Designed by Spanish engineer Agustin de Bétancourt with a unique roof without internal support for 45 m, it was erected from 1817 to 1825 by the Russian architect Joseph Bové, who clothed it in its Neoclassical exterior, an order of Roman Doric columns enclosing bays of arch-headed windows in a blind arcade, painted white and cream yellow. The roof, with its internal rafters and beams exposed, rests on external columns of the Manege. The structure was used first as a traditional manège, to house parades of horsemen and a training school for officers. The Manege was large enough to hold an entire infantry regiment—over two thousand soldiers— as well as an invited audience.
