Valadier Temple, Italy

Located in the central Italian region of Marche, about one hour drive west of the city of Ancona, this gorgeous temple designed by the Italian architect Giuseppe Valadier in 1828 was originally a refugee for Christian pilgrims.

The temple is at the entrance of the Frasassi caves complex, whose Abisso Ancona is one of the biggest cave chambers in the world, 180 meters long and 200 meters tall, enough to accommodate the Milan Cathedral.

Beside the temple stands the Sanctuary of Santa Maria Infra Saxa, built in 1029 and completely carved into the rock.
