Considering the value of the contemporary architecture from Porto, such as the two Pritzker’s Álvaro Siza Vieira and Eduardo Souto de Moura, the Open House Porto also features historical buildings located in a wider area that embraces Porto, Matosinhos, Vila Nova de Gaia and Maia. From towers, lighthouses, theaters, museums, schools, offices, infrastructure, or private houses, different typologies can be visited on one weekend in July.
