Museo de Arte en Vidrio de Alcorcón: Contemporary Glass Art

The Castillos de San José de Valderas, also known as Castillos de Valderas, were commissioned by the Marquis of Valderas and built starting around 1916 by architect Luis Sainz de los Terreros. The main palace was inaugurated in 1917, with two smaller adjacent buildings for a chapel and servants.

During the Spanish Civil War, starting in November 1936, the main castle was used as a frontline military headquarters for the sublevada zone. Francisco Franco and Emilio Mola stayed there during offensives on Madrid.

After the Civil War, the castles fell into ruin. In 1952, the finca and buildings were sold by the Marquis of Valderas's daughter to the construction company Sanahuja, marking the beginning of the San José de Valderas neighborhood development.

The Alcorcón City Council began the acquisition process for the castles in 1985, which was finalized in 1988 when the VI Marquis of Valderas donated them to the municipality.

In January 1991, the Alcorcón City Council commissioned a renovation and restoration project for the castles, focusing on preserving their external appearance while modernizing the interiors for cultural use. The project had a budget of 1000 million pesetas and a 22-month execution period.

The Museum of Glass Art of Alcorcón (MAVA) was established in 1997, initiated by sculptor Javier Gómez, with the goal of promoting glass as a medium in contemporary art. Its initial collection comprised donations from the Takako Sano collection and direct artist donations.

The initial permanent collection of the Museo de Arte en Vidrio de Alcorcón (MAVA) was formed by over sixty works donated by Takako Sano from her private collection, alongside 107 works directly donated by various artists.

A request to declare the Castillos de Valderas a Bien de Interés Cultural (BIC) was submitted in 2017, coinciding with the centenary of the main castle's inauguration. This designation recognizes its cultural and historical importance.

The construction of the Centro de Creación de las Artes de Alcorcón (CREAA), a large cultural complex within the park, began in 2007 under Mayor Enrique Cascallana. However, the project was halted due to the economic crisis.

The construction of the CREAA was stopped in 2011 by Mayor David Pérez due to the economic recession's impact on the local government. The ambitious project, spanning 66,000 square meters, was left unfinished.

In 2022, plans were announced for a 32 million euro investment to create a national reference center against gender violence at the former CREAA site, in collaboration between the Ministry of Equality and the Alcorcón City Council.
