St. John the Baptist Cathedral, Santorini (must see)

The Catholic Cathedral of Saint John the Baptist stands out as the principal Roman Catholic church on the island. Originally established in the 17th century during the period of Venetian influence, it reflects the Catholic presence fostered by Western religious orders, including the Jesuits. Like many buildings on Santorini, it was repeatedly affected by seismic activity. The structure seen today dates from a reconstruction completed in 1975, carried out in a restrained, Baroque-inspired style.

Approaching the cathedral, notice the peach-colored facade, which immediately distinguishes it from the island’s predominantly whitewashed Orthodox churches. The clock tower and bell tower, rising just to one side, serve as an easy visual marker from nearby streets.

As you step inside, pause near the entrance. To one side, you’ll find the confessional, a feature typical of Catholic churches but rarely encountered elsewhere on the island. Moving forward into the nave, your eye is naturally drawn toward the main altar, positioned beneath the dome and arranged according to Western liturgical tradition rather than behind an iconostasis.

Lift your gaze upward to the central chandelier, suspended below the dome. Its placement reinforces the height of the space and acts as the visual center of the interior. Above the altar, a large religious painting forms the focal point of the sanctuary, framed by soft blue, cream, and warm-toned surfaces that emphasize light and balance over heavy ornamentation. Along the side walls, look for a series of framed devotional paintings and portraits of saints, arranged in a clear, orderly sequence.

The cathedral remains an active place of worship, serving both local parishioners and visitors. Sunday Mass is regularly held, often attended by an international congregation, with parts of the service occasionally offered in multiple languages depending on those present. Visitors are expected to dress modestly and maintain a respectful atmosphere, especially during services.

Outside, the surrounding streets form part of Fira’s compact commercial center, with small shops, cafes, and casual eateries unfolding just beyond the church—an everyday setting that contrasts with the quiet, ordered interior you have just explored.
