Fodor's Expert Review Torre dos Clérigos

Designed by Italian architect Nicolau Nasoni and begun in 1754, the baroque tower of the Igreja dos Clérigos is the tallest in Porto and a landmark on the city's horizon. There are 225 steep stone steps to the belfry, and the considerable effort required to climb them is rewarded by stunning views of the red-roofed Old Town and the mouth of the Douro River. Binoculars and audio tours are available for an extra charge. The church itself, also built by Nasoni, predates the tower and is an elaborate example of Italianate baroque architecture. Admission includes access to a small museum.
