Medieval Tunnels Medieval tunnels under the castles always conjure up myths and creepy night time stories. Here you will find a listing and descriptions of the castles that have tunnels or underground passages.
Steps lead down from the inner ward to a dark cave and passage.
At the end of the cave is a reservoir. Human remains, from prehistory time, were found here. A staired underground passage leads into the rock to a cave. It is called the Wogan. An underground passage runs from the basement of the great tower to the kitchen block basement.
