Ricardo Velázquez Bosco (Burgos 1843 – Madrid 1923) was a Spanish architect, archaeologist and scholar.
Velázquez's most notable architecture was erected in Madrid, buildings such as the Palacio de Cristal and the Palacio de Velázquez (both in the Parque del Buen Retiro) and the massive Ministry of Agriculture building. As an architect he was known for the prolific use of glazed pieces of ceramics in bright colors for his projects. He also carried out restoration work on the Cathedral–Mosque of Córdoba and directed important archaeological excavations near Córdoba.
Use of ceramics as decorative architectural materials became popular in Spain in the late 19th century and early 20th century. Architects such as Velázquez used them in the style which came to be known as “Regionalist Architecture". Velázquez built the Palacio de Velázquez, which is named after him, in the Parque del Buen Retiro in Madrid. This building, which was constructed for the Exposición Nacional de Minería (1883), features ceramic tiles made by Daniel Zuloaga.
The Palacio de Velazquez and the nearby Palacio de Cristal are influenced by London's Crystal Palace. Velázquez taught the Spanish architect Antonio Palacios who was influenced by his eclectic and modern style; it is sometimes called "emphatic eclecticism". His works are characterized by a resounding treatment of volume, as well as the use of ceramic decoration on building facades. He was a member of the Real Academia de Bellas Artes de San Fernando along with Enrique María Repullés and Narciso Pascual Colomer. Most of his work was concentrated in Madrid, where he taught at the School of Architecture.
