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.
Casa da Música was planned as a home for all types of music and it is not only part of the urban redevelopment of Porto but also part of a network of cultural facilities, for the city of Porto and for the wider world. Underlying it is an innovative and wide-ranging cultural project, which aims to make an exciting contribution to the national and international music scene, as an arena for all types of musical events - from classical music to jazz, from fado to electronic music, from great international productions to more experimental projects.
Besides concerts, recitals and other types of performance, Casa da Música also organises events for musicians and musicologists and invests in research into the origins of Portuguese music. In addition, it plays a very important role in music education. It is a cultural meeting point between music and other areas of artistic creation and knowledge, providing a space for all kinds of audiences and creators.

Porto is an amzing city with a lot of very interesting historical sites. I suggest to not waste time with such modern construction, unless you really want to see a specific concert. The building is beautiful and it is easy to see when walking around the city

Porto in total is a nice city with interesting and impressive architecture. Casa da Musica wasnt that special for me but worth a visit if u have time in Porto. But the wineyards and the city itself will impress u more, I guess.
