Baszta Męczarnia

Torture Tower, (or, to be precise, a Corner of Town Wall Tower of Sufferings) fully reconstructed, open for guided tours from April to October.

It's next door to my family home but as they only completed it after I left, I've never been inside. 

Well, I have, but it was only the stone part then, it had no roof and it was basically a camping spot for homeless drunks. And underage drunks. And drunks on their way home. 

Hopefully they blasted it really thoroughly with bleach inside...
