Chopera | Paseo de la Chopera Matadero Madrid is a former slaughterhouse which has been converted to an arts centre. It was then called El Matadero y Mercado Municipal de Ganados. The project of the slaughterhouse and livestock market was structured around a complex of pavilions characterised by functionality, constructive rationality and conceptual simplicity. There is however a historicist element to the architecture, which incorporates Neo-Mudéjar features, such as tiles with abstract designs. Arch. Luis Bellido y González 1910-25 Arch. Francisco Javier Ferrero Llusiá 1932-33 The buildings were in use as a slaughterhouse until 1996.
