St. John's Co-Cathedral — Chapels

Background: What’s a Langue Chapel?

Each of the eight official “langues” (linguistic divisions of the Knights of St. John) had its own chapel, serving as both spiritual center and a showcase of their wealth and prominence. These chapels are exquisitely decorated with art, funerary monuments, and altarpieces, often reflecting the artistic direction of the Baroque period. A ninth chapel, the Chapel of Our Lady of Philermos, was dedicated to the Order's patroness.
