Completed in 1578, St John’s Co-cathedral in Valletta (Malta), was founded by the order of the Knights of St John. Its severe facade contrasts with the richly decorated interior, where decorated chapels represent the langues (regional administrations) of the Order’s members: Auvergne, France, Provence, Aragon, Italy, Germany, Castile, Léon and Portugal, and Anglo-Bavaria. A sumptuous example of the European roots of the Order and tangible expression of a Europe united in diversity.
