St. Paul's Cathedral in Mdina was built on the site where governor Publius was reported to have met Saint Paul following his shipwreck off the Maltese coast. According to tradition, the first Cathedral of Malta was dedicated to the Blessed Virgin, Mother of God but, having fallen into ruin during the Muslim period, it was rebuilt following the Norman conquest and re-dedicated to St Paul. The old church was modified and enlarged several times.
The building we can see today was designed by the architect Lorenzo Gafa, it was built between 1697 and 1702 to replace a ruined Norman cathedral destroyed by the 1693 earthquake on Malta. Despite this, several artifacts and edifices survived including the painting by the Calabrian artist Mattia Preti depicting the conversion of Saint Paul, a 15th-century Tuscan painting of the Madonna and Child, and frescoes in the apse which illustrate Paul's shipwreck.
The architect Lorenzo Gafa designed the Cathedral in Baroque style. It sits at the end of a rectangular square. The near-square facade is cleanly divided in three bays by the Corinthian order of pilasters. There are two bell towers at the both corners. The plan is a Latin cross with a vaulted nave, two aisles and two small side chapels. The Cathedral has a light octagonal dome, with eight stone scrolls above a high drum leading up to a neat lantern.
One of the main features of the interior is the rich colorful tessellated floor. Many of the furnishings of the cathedral, including the baptismal font and the portal, are carved out of Irish wood.
The cathedral also has a substantial collection of silver plates and coins, and some carvings by the German artist Albrecht Dürer.
References: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.
