The Great Siege Tunnels were made by the British at the end of the 18th century to fend of the Spanish and French. It’s pretty amazing the work that went into carving out the tunnels. Not to mention how they got the huge cannons up there. I’m thinking that they must have had some short people in the “old days” because sometimes there was enough room for me to stand, and sometimes, not so much. As a rule, I don’t like walking around places where I may bash my head into the ceiling, so I waited back at the car while the rest of the (shorter) family continued on.
