Sitting in the midst of a cave, the Temple of Valadier seems bizarrely out of place.
Located nearby Ancona, Italy, a small port city. The Temple was built in 1828 by architect Giuseppe Valadier and uses white travertine.
This spot is believed to have been used as a sanctuary from invaders as early as the 10th century. The Temple has an octagonal shape and was commissioned by pope Leone XII.
The Frasassi Caves are located in the vicinity. With names like the Sword of Damocles, Little Niagara Falls, and Slice Of Bacon you begin to get a picture of the unique limestone formations inside.
