A Potty Museum

From Atlas Obscura -

Museum of Historical Chamber Pots and Toilets
Dedicated to the unsung history of human waste.

There is a small museum in Prague, not far from the Vltava River, that is truly a celebration of “form follows function.” In its collection of historical chamber pots and toilets there is a wide array of forms, all for one bodily function (or maybe two).
