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, who admires them as objects. Highlights are currently on display in the town’s National Archaeological Museum (until 31 October). The courtyard of its Renaissance palazzo has rows of them, and the sheer weight of the cast iron means they can be left without too much security.
