The Casa da Música is a concert hall in Porto, Portugal. It was designed by architect Rem Koolhaas and opened in 2005. Designed to mark the festive year of 2001 in which the city of Porto was designated European Capital of Culture, it was the first building in Portugal aimed from its conception to be exclusively dedicated to music, either in public performances or in the field of artistic training and creation. Casa da Música's project was set in motion in 1999 as a result of an international architecture tender won by the project presented by Rem Koolhaas - Office for Metropolitan Architect
