St John’s Co Cathedral was built as a church for The Knights of St John, the Grand Masters and several Knights, would donate gifts of high artistic value and used to do huge contributions to enrich this church, with the finest and best works of art. Today it is a gem of Baroque art, architecture, and an important sacred shrine of worship.
The Cathedral is testimony to the talent of Maltese military architect Gerolamo Cassar, with Mattia Preti’s intricately carved stone wall designs, as well as the painted vaulted ceiling and side altars with scenes from the life of St John. The Cathedral also houses one of Europe’s most impressive and famous art works – Caravaggio’s Beheading of St. John the Baptist. The Cathedral was a shrine to the Knights, as many sons of Europe's noble families from the 16th to 18th centuries lie buried here. Their intricate, marble-inlaid tombstones form a magnificently crafted pavimento. Also a resting place to the founder of Valletta, Grand Master Jean Parisot de la Vallette, his tomb lies in the crypt, a quiet sanctuary and place of contemplation away from the busy streets outside.
