St John’s Co-Cathedral is a gem of Baroque art and architecture. It was built as the conventual church for the Knights of St. John. The Grand Masters and several knights donated gifts of high artistic value and made enormous contributions to enrich it with only the best works of art. This church is till this very day an important shrine and a sacred place of worship. It is also a venue for cultural events.
Described as the first complete example of the high Baroque anywhere, St. John’s Cathedral epitomises the role of its original patrons, the Knights of St. John. 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.
