The Cathedral / Cathedral of Oporto, located in the historic center of Porto, is one of the leading and oldest monuments in Portugal.
The beginning of its construction dates from the first half of the twelfth century and lasted until the beginning of the thirteenth century. This first building in Romanesque style, has undergone many changes over the centuries. Romanesque time they date the general character of the facade with the towers and the beautiful rose window, beyond the body of the three-nave church covered with barrel vault. The central nave of the vault is supported by flying buttresses, the Porto Cathedral being one of the first Portuguese buildings which used this architectural element.
In the Gothic era, about the year 1333, he built up the funeral chapel of João Gordo, Order of the Knight of the Hospitallers and collaborator of King Dinis, buried in a tomb with recumbent. Also from the Gothic period date the cloister (century XIV-XV), built in the reign of John I. This king married Philippa of Lancaster in Port Cathedral in 1387.
The exterior of the Cathedral was very modified in the baroque period. Around 1736, the Italian architect Nicolau Nasoni added beautiful baroque church porch to the side facade of the Cathedral. Around 1772 built a new portal to replace the original Romanesque. Balustrades and cupolas of the towers are also baroque.
