Housed in a 17th-century manor house, restored and equipped with the latest museological techniques, the Gregorio Prieto Museum was inaugurated by His Majesty the King of Spain on February 19, 1990.

The Gregorio Prieto Foundation was established in 1968 in the cave of Medrano, as the painter’s wish to donate his entire body of work to the Spanish people. In 1987, by the express wish of Gregorio Prieto, the Foundation was moved to the city of Valdepeñas, with the first phase of its museum opening in 1987. However, it wasn’t until 1990 that His Majesty the King inaugurated the entire museum.

The Museum is located in a typical 17th-century Manchego house, properly restored to house the art collection. This collection contains nearly 6,000 works, the majority created by Gregorio Prieto, but the Museum also owns works by other 20th-century artists such as Picasso, Pissis, Chirico, Vázquez Díaz, Bacon, and others. It also includes a collection of original drawings by Federico García Lorca and Rafael Alberti, as well as collections of polychrome wooden religious carvings from various centuries.

A tour of the Museum’s rooms allows visitors to appreciate the evolution of Gregorio Prieto’s work, from his impressionist period to surrealism, passing through the Greek and Roman periods and his postism phase, where surrealist and metaphysical photographs, so characteristic of this movement, stand out. Postism was introduced to the art world by the brilliant artist from Valdepeñas and Eduardo Chicharro from Rome, with Francisco Nieva, Edmundo D’Ory, and Juan Alcaide being some of its foremost representatives.
