The International Manhole Cover Museum must surely rank as one of the world’s most bizarre collections.
It was set up by Stefano Bottoni, from Ferrara, in northern Italy.
Some of the covers were on temporary outdoor display.
The sheer weight of the cast iron means they can be left on outdoor display with minimal security.
The manhole covers are from all over the world including Amsterdam, Havana, Helsinki, Prague, Rome, Bucharest, Sarajevo and Vienna.
The museum lends dignity to objects that give access to storm drains, sewers, underground pipes, etc.
