The catacombs include an estimated 5.5km of tunnels containing the graves of more than 15,000 local Christians, mostly from the 4th and 5th centuries AD. The only section open to the public is about 100m of the Catacombes du Bon Pasteur, named after an engraving of the bon pasteur (good shepherd) found inside. Most of the graves have been bricked in; a few have glass fronts, revealing skeletal remains.
