Toilets, bedpans and other must-haves for nature's calls from around the world are on display at a museum in Prague that claims to be the largest of its kind.
"We bought a 10th-century fortress near Prague and discovered a historic toilet there," says Jan Sedlacek, a 59-year-old civil engineer and head of the Museum of Historical Chamber Pots and Toilets.
"That's how it started: we wanted to know how people did it back then," he told AFP, pinpointing the moment he became a toilet collector.
The museum, which opened at the fortress in 2010 and moved to Prague this year, now boasts 2,000 items, which Sedlacek says makes it the world's largest ahead of similar venues in India and Spain.
"We keep looking for items with history," he said, pointing to a bedpan made out of a World War II German army helmet.
The collection also features a hard-to-get Japanese "Washiki" squat toilet, a bedpan built for Napoleon and portable urinals used by women during long sermons delivered by the 17th-century French preacher Louis Bourdaloue."The most precious exhibits are the price of a very decent car," Sedlacek said.
Spanning two storeys of an old house, the museum welcomes around 600 people a month - revealing secrets old and new.
"Some see a bedpan with a lid and cry: 'Look, Jesus, we've been eating soup out of this our whole lives!'" Sedlacek said.
