Porto Cathedral

The Porto Cathedral is the most important religious edifice in the city of Porto, and it has been declared a national monument. It is located near the walls that previously protected the city, and its building somewhat resembles a castle with arches from the outside. The construction of the cathedral began during the twelfth century, but It was rebuilt and renovated several times over the centuries, which explains why the cathedral is a mixture of different architectural styles such as Baroque, Romanesque and Gothic styles.
