The cathedral in Porto is a Roman Catholic church dedicated to the Assumption of the Blessed Virgin Mary. It is on the UNESCO World Heritage List. Inside the temple you can see Renaissance altars, a 17th-century presbytery and a Rococo entrance door. Noteworthy are the azulejos from the 18th century by Valentima de Almeida, which will depict the life of the Virgin Mary.
The building was erected in the 12th and 13th centuries in the Romanesque style. Its construction was initiated by Bishop Hugo. Originally, it also fulfilled defensive functions. Merlons and towers, as well as thick and high walls have survived to this day. In the fourteenth century, the cathedral received Gothic windows. At that time, monastery rooms were added, and in the 18th century the cathedral was rebuilt in the Baroque style under the direction of Nicolau Nasoni.
