Torre dos Clérigos

This guide to the Torre dos Clérigos in Porto starts on unlikely ground: the hill it stands on was once known as the Hill of the Hanged Ones, the city's old execution grounds. It follows Nicolau Nasoni, the Italian architect who fell in love with Porto and gave the Brotherhood of the Clérigos an oval church and, when funds ran short for the two towers he wanted, a single soaring one instead. Best heard while climbing the narrow stone stairwell inside, on your way up toward the belfry.
