The French village of Aubeterre-sur-Dronne, a commune in the Charente department in the Nouvelle-Aquitaine region of southwestern France, has been listed as one of the most beautiful villages of France since 1993. Part of its beauty lies in its architectural treasures, including the 11th-century Chateau d’Aubeterre, literally Aubeterre Castle, and the spectacular Church of Saint Jean, one of the largest underground churches in the world,is also known as, or the Monolithic church, or the Eglise Monolithique, or the Troglodyte Church. This church was dug in the 12th century. The main purpose of constructing this church was to preserve the relics. This unusual monolith has been created out of the wall of limestone. Take a flight of stairs to descend to the church. It is one of the churches created in the underground level. The spooky graves dug in a part of the church evoke fear. Despite the high temperatures outside, the church offers a cool respite.
