The finest specimen of baroque architecture in the city is the church of Santa Barbara, now adjoining the Palace of Justice, and formerly the church of a convent founded in the time of Ferdinand VI. The building is in the form of a cross, with towers, and an ornamental façade. The dome is decorated with frescoes, and the marble altarpiece is especially graceful. Olivieri carved the figures of St Ferdinand, St Barbara, and Faith and Charity on the retablo. The tomb of Ferdinand VI. by Sabatini is in the transept. There is also a monument to General O’Donnell, designed by Jeronimo Suñol. San Ginés should be seen for the picture of the “Scourging of Christ” by Alonso Cano, and a statue of Christ by Vergara. Madrid compares unfavourably with other capitals as regards buildings. Of late years a good many new edifices have arisen, but these are massive and pretentious rather than imposing. The Plaza Mayor--originally the market-place of Madrid--is historically interesting as the scene of numerous autos de fé and bull-fights, while the architecture of the Casa Panaderia should be examined. The building contains pictures by Coello. In the middle of the square is the statue of Philip III. on horseback, cast in bronze, and the work of Juan de Bologna and his pupil Tacca. A monument of the time of Philip IV. is seen in the offices of the Ministry of State, formerly a prison. It was designed by the Italian Bautista Crescenti, with figures by Herrera. The Town Hall is seventeenth century, with a good façade, and a fine staircase. In the oratory of this building are pictures by Palomino. Very little remains of the old palace of the Buen Retiro, which has been converted into the Artillery Museum. The Palacio del Congreso (House of Commons), finished in 1850, is Corinthian in style. There is a fine allegorical group by Ponzano, who also designed the lions on the front. Within, there are frescoes of historic scenes. The largest square in Madrid is the Plaza de Oriente, constructed by order of Joseph Buonaparte. There are fourteen immense statues of kings in this open space, and a beautiful fountain with lions in bronze. The equestrian statue of Philip IV. is by Tacca, from a painting by Velazquez; its equilibrium is said to have been determined by Galileo. The Museum of Archæology, already mentioned, has many objects of antiquity dating from prehistoric times. There are a number of Roman remains, Moorish relics, treasures from China and Mexico, and curiosities of many kinds. In “Castilla La Nueva” Don Jose Quadrado refers to the old door of the Monte de Piedad, in the Plaza de las Descalzas, as an interesting relic. It is surmounted with a very ornate bell, and there are two female torsos, and some good carving on the frontage.
