Seat of the Assembly of Madrid

The Seat of the Assembly of Madrid (Spanish: Sede de la Asamblea de Madrid) is located in the neighbourhood of Palomeras Bajas in the Puente de Vallecas district of Madrid.

The Assembly of Madrid had been held in the city centre at the Caserón de San Bernardo. When a plan to move to Retiro was vetoed by the city council due to residents' complaints, Assembly president Pedro Díez proposed moving to the new site, and construction started in April 1995. The site opened in September 1998, at a cost of 3 billion Spanish pesetas.

The design of the main chamber as a glass cube within a triangular building was carried over from the plan for Retiro, although scaled down due to the smaller new site. The building houses a painting by Antonio López García and a mural that was the last work by Lucio Muñoz.
