Plaza de Isabel II

The Plaza de Isabel II (also known as Plaza de Ópera) is a historic public square between the Sol and Palacio wards in the central district of Madrid. The plaza is at the convergence of Arenal Street (from the Puerta del Sol) and the minor roads Arrieta, Calle de Campomanes, Caños del Peral, Escalinata and Vergara. It was formed by filling the ravine created by the Arenal stream and the source of the Fountain of the Canals of the Pear Tree. The square occupies part of the site where the old Theater of the Caños del Peral stood between 1738 and 1817.
