The parish church is dedicated to Saint Aelhaiarn, but has sometimes been erroneously recorded as dedicated to Saint Giles, All Saints, and Saint Tysilio. The church is a very well-preserved 14th century church with an earlier tower, on the site of a pre-Norman church perhaps founded by the saint himself. There is an exceptional 14th century nave roof and a painted Tudor ceiling in the chancel. The tower of the present church dates to about 1300.
The Cathedral of Saint Mary Major, often called Lisbon Cathedral or simply the Sé, is a Roman Catholic cathedral located in Lisbon, Portugal. The oldest church in the city, it is the seat of the Patriarchate of Lisbon. The cathedral has survived many earthquakes and has been modified, renovated and restored several times. It is nowadays a mix of different architectural styles.
The site where it stands was the principal mosque of Lisbon when it was an Arab settlement. The construction of the cathedral started around 1150, three years after the city was conquered from the Moors during the Second Crusade. Shortly after the victory the English knight Gilbert of Hastings was named bishop of the city of Lisbon.
One good reason to visit the Cathedral is to visit its charming cloisters located in the back. There are several tombs in the cathedral, the most notable of which is the beautifully sculpted tomb of Lopo Fernandes Pacheco and his wife.
