The 16th century old cathedral (Hubble, if you will) is now a museum. It has six small crypts, the largest of which has been restored and opened to the public --its bones removed. It is dim, dank and would make a great setting for a scary story. As you go down the steep narrow steps, an earthy smell takes over. Once your eyes adjust to the din, the stone and brick tunnel leading to a small chamber comes into focus. The benches are actually "rotters", surfaces where bodies were laid and covered with lime to speed the process of freeing the bones from the flesh. A large pit at the center of the chamber is the ossuary, once filled with bones.
