The Porto Cathedral began to be built in the twelfth century, but over the centuries it received influences of the Renaissance, Baroque and Rococo periods.
Just the architecture of the Cathedral of Porto is sufficient to be considered one of the jewels of the city. The Gothic initial construction, conspicuous in the cloister and the Chapel of São João Evangelista, together with the singularity of the Blessed Sacrament Chapel and its silver altar. The Baroque of the eighteenth century is present in the frescos of the chancel and sacristy, by Nicolau Nasoni, and in the tiles of the cloister.
The interior of the cathedral is a real treasure, with invaluable furniture, consisting of tables and sinks in rare marble, the mirrors trims, cabinets and a black wood clock in Rococo style.
Outside, the patio of the cathedral is surrounded by the buildings of the Cathedral, the canon house, Episcopal Palace and Town Hall. It is one
of the privileged viewpoints in the city. From that point it is possible to behold the area of Barredo, the River Douro and the city of Gaia.
