No external inscription on vault/mausoleum. All names supplied are from local knowledge. There are more than five people interred within the mausoleum as inside there is supposedly a door in the floor leading down to a further chamber with additional remains. It is unknow as to who these are. The mausoleum measures approx. 7 m by 4 m.
