Muzeum Kanalu 
Description
Museum of the Sewer. A tour guide takes you on a short (20 minute) tour round this circular former flushing sewer underneath Plac Wolnosci. The structure itself wasn't actually a sewer but used to hold water that would then be flushed down into the various sewers of the city to clean them - hence why it's now safe to take tourists round on tours.
