Spanish Baroque is a strand of Baroque architecture that evolved in Spain, its provinces, and former colonies.
As Italian Baroque influences penetrated across the Pyrenees, they gradually superseded in popularity the restrained classicizing approach of Juan de Herrera, which had been in vogue since the late sixteenth century. As early as 1667, the facades of Granada Cathedral (by Alonso Cano) and Jaén Cathedral (by Eufrasio López de Rojas) suggest the artists' fluency in interpreting traditional motifs of Spanish cathedral architecture in the Baroque aesthetic idiom.
In Madrid, a vernacular Baroque with its roots in Herrerian and in traditional brick construction was developed in the Plaza Mayor and in the Royal Palace of El Buen Retiro, which was destroyed during the French invasion by Napoleon's troops. Its gardens still remain as El Retiro park. This sober brick Baroque of the 17th century is still well represented in the streets of the capital in palaces and squares.
In contrast to the art of Northern Europe, the Spanish art of the period appealed to the emotions rather than seeking to please the intellect. The Churriguera family, which specialized in designing altars and retables, revolted against the sobriety of the Herreresque classicism and promoted an intricate, exaggerated, almost capricious style of surface decoration known as the Churrigueresque. Within half a century, they transformed Salamanca into an exemplary Churrigueresque city.
The development of the style passed through three phases. Between 1680 and 1720, the Churriguera popularized Guarini's blend of Solomonic columns and composite order, known as the "supreme order". Between 1720 and 1760, the Churrigueresque column, or estipite, in the shape of an inverted cone or obelisk, was established as a central element of ornamental decoration. The years from 1760 to 1780 saw a gradual shift of interest away from twisted movement and excessive ornamentation toward a neoclassical balance and sobriety.
