The worst experience we've had in Albania!!!
We went through the entrance gate and the tower was closed. A woman (who lived in the house next to the tower) came and said she could open it and show us around. When we paid her to do that she said she didn't have the keys. When we asked for our money back she accused us of trespassing and said she'd call the police
Stay outside of the fence, if you don't want the same to happen to you
