Tunnels in Kilkenny City
Recently I've heard that there is a whole network of catacombs in Kilkenny City, which wouldn't be all that unfitting, considering its history.
I hear they are entered from the crypt in St Mary's Cathedral (that door at the back with the skull and crossbones on it) and many other places too.
There is an interesting trap door in the street level of the Tholsel (town hall) that may lead to them, as well as that tunnel in the Rose Garden of the castle and I'm sure there are many other entrances. Surely St. Canice's Cathedral and St. Kieran's College have entrances too...
Does anyone know anything about them, or even been in them?
