Collegiate Church of Santa Maria a Mare

The cathedral of Amalfi is composed of two churches: the first one was founded in the 9th century, and in 987, another church was built right next to the cathedral. Soon the two churches, both with three naves, were joined together and thus formed a single Romanesque church with six naves. In the period following the Counter-Reformation, the two buildings became separate again and the older one became the Basilica of the Crucifix, leaving the title of caricature to the building of 987. Other interventions took place between the 16th and 18th centuries. The present façade was built in the 19th century by Errico Alvino assisted by a group of architects. The bell tower of St Andrew's Cathedral was built between 1108 and 1276.

The church of San Pietro dates back to the end of the 10th century but its neoclassical structure is due to reconstruction in the 17th century. The bell tower, which sticks to the facade of the church, dates back to the 11th century. The church is typical of the Amalfi coast for its dome covered with coloured tiles.

The Abbey of the Holy Trinity of Cava de' Tirreni is a Benedictine abbey founded in the 11th century and raised to the status of a territorial abbey in 1394, thus having the status of an abbey cathedral. The founder of Cava Abbey was Saint Alferius, a nobleman from Salerno who was trained at the Abbey of Cluny. In 1011 he retired to the great Arsiccia Cave to spend a hermit's life, which attracted many followers in order to build a small monastery, the original nucleus of today's abbey.
