|Santa Maria Maior de Lisboa or SÚ de Lisboa is the cathedral of Lisbon and the oldest church in the city. Since the beginning of the construction of the cathedral, in the year 1147, the building has been modified several times and survived many earthquakes. It is nowadays a mix of different architectural styles.|
Lisbon is the seat of a bishopric since the 4th century AD (see Patriarch of Lisbon). After the period of Visigothic domination the city was conquered by the Moors and stayed under Arab control from the 8th to the 12th century, although Christians were allowed to live in Lisbon and its surroundings. In the year 1147, the city was reconquered by an army composed of Portuguese soldiers led by King Afonso Henriques and North European crusaders taking part on the Second Crusade. An English crusader named Gilbert of Hastings was placed as bishop, and a new cathedral was built on the site of the main mosque of Lisbon.
