Casa da Música | 11,471 followers on LinkedIn. Casa da Música was conceived to mark 2001, the year in which Porto was Cultural Capital of Europe, and it is the first new building in Portugal to be entirely dedicated to music - to the presentation and public enjoyment of music, to music education and to the creation of music. The project took shape in 1999 after the Rem Koolhaas & Ellen van Loon - Office for Metropolitan Architecture won the international architectural competition. Work began in 1999 on the site of Porto's former central tram garage on the Rotunda da Boavista, and Casa da Música opened its doors to the public on April 15th , 2005.
