This is the coolest place I’ve been to so far. Bective Abbey is this great ruin of a stone Abbey that was the base for the order of, er, something monks. Farm Boy knows but he just left the room. The best part about it is that you can just wander around on your own and climb all over the ruins. The Farm Boy and I had a lot of fun acting like kids climbing and jump and generally making more noise than an Abbey should have.
There was one room on the second floor still intact, but they had gates across the doors so you couldn’t get to it.
To get there you have to tromp through a field of cows, then climb stone steps and go over the wall, rather than through the gate.
