Montefiascone Cathedral, Renaissance-Baroque cathedral in Montefiascone, Italy

Montefiascone Cathedral, dedicated to Saint Margaret of Antioch, has a lower church and an upper church. Its ribbed dome by Carlo Fontana, 27 metres in diameter, rises on a drum and is visible from most towns of the Viterbo area. The 1840 west front has two bell towers, Ionic columns and statues of Saints Flavian and Margaret.

Pope Urban V made the church the cathedral of the new Diocese of Montefiascone in 1396. Cardinal Domenico della Rovere ordered a larger replacement in 1478, begun in 1483 under Antico di Stefano; Michele Sanmicheli took over in 1519 and designed the dome. A Good Friday fire in 1670 destroyed the roof, and Carlo Fontana rebuilt the dome, inaugurated on 16 December 1674.

The interior preserves marble statues, relics of Saint Margaret of Antioch, Saint Lucia Filippini, and houses the tomb of Cardinal Marco Antonio Barbarigo.

The building is located at Piazzale Santa Margherita and can be seen from various points across Viterbo province. Its central position in Montefiascone makes it easily accessible for visitors exploring the cathedral.

Inside are marble statues and relics of Saint Margaret of Antioch, as well as the tomb of Cardinal Marco Antonio Barbarigo. These artworks and sacred objects make this cathedral an important destination for art lovers and pilgrims.
