History and Significance

St. John's Co-Cathedral was constructed shortly after the founding of Valletta, intended as both a house of worship and a statement of prestige for the Knights of St. John. The building's fortress-like exterior mirrored the disciplined, militaristic nature of the Order, while the interior reflected its wealth and religious fervor. Initially simple in design, it underwent a lavish Baroque transformation in the 17th century under Grand Master Raphael Cotoner, who commissioned artist Mattia Preti to paint its dramatic vaulted ceilings.

Each Langue (national division) of the Knights had its own chapel within the cathedral, leading to friendly competition over which could be the most elaborately adorned. These chapels remain among the most ornate in Europe, filled with gilded altarpieces, marble statues, and symbolic imagery. The floor itself is a masterpiece — more than 400 inlaid marble tombs commemorate knights and commanders, their coats of arms and Latin inscriptions immortalizing centuries of service and sacrifice.

Things to See and Do

The undisputed highlight is Caravaggio’s “The Beheading of Saint John the Baptist,” displayed in the Oratory. This is the artist’s only signed painting and one of the most powerful depictions of martyrdom in art history. The nearby “Saint Jerome Writing” showcases Caravaggio’s signature use of light and shadow, offering insight into his time in Malta.

Visitors can wander through the side chapels, each dedicated to different national groups of the Knights, marveling at their unique decorations. The vaulted ceilings painted by Preti depict scenes from the life of St. John and seem to shimmer in the light filtering through the high windows. Beneath your feet, the marble floor adds another layer of beauty and reflection, each tombstone a work of art in itself. This spot is one of the best places to see in Valletta and a highlight of any walking tour of Valletta, where faith and art converge on an unparalleled scale.
