The cathedral floor features approximately 400 marble tombstones, each marking the burial site of a Knight of the Order of St John.
Caravaggio's 'The Beheading of Saint John the Baptist' is the only painting signed by the artist.
The Cathedral's interior walls were carved directly from the local limestone, then gilded to create a stark contrast with the painted ceilings.
The set of 29 Flemish tapestries, based on designs by Rubens and Poussin, is one of the largest and most complete sets in the world.
The Co-Cathedral was named such because the Bishop of Malta holds his seat here, sharing the title with the Cathedral in Mdina.
St John's Co-Cathedral is a high-baroque masterwork commissioned by the Order of St John in 1572 and designed by architect Girolamo Cassar. The interior is defined by intricate carved stone walls, painted vaulted ceilings by Mattia Preti, and a floor comprised of nearly 400 inlaid marble tombstones of knights. It serves as both a place of worship and a repository for historical artifacts, including two original paintings by Caravaggio. The museum wing houses a collection of Flemish tapestries, liturgical vestments, and silver plate. The building is located in the heart of Valletta, distinct from the residential suburb of Sliema listed in the prompt's database, confirming its identity as the landmark in Malta's capital. Visitors move through the Oratory, which holds the famous 'The Beheading of Saint John the Baptist'.
