The underground spaces are entered through a small and narrow lobby, whose door are also cut into the live rock. In the late 19th or early 20th century, this entrance into the Catacombs was covered with a vaulted entrance at ground level, which was conceived as a protection from elements. There are unfinished carved figures on the lobby's
rockface on the both sides of the door, just in front of the narthex. On the left is a male figure, probably holding a spear in one hand, and a lowered sword in the other. To the left, next to a figure, hardly discernible, there is a depiction of what appears to be a heraldic image, with a large helmet and a
mantle descending behind the
shield, or was supposed to be the top of the helmet, from which springs a hand bent at the elbow with a sword. On the other side is also a carved representation of a female figure with a heraldic sign in her left hand, most likely a
fleur-de-lis. ==National monument==
