Mole Antonelliana
You can't miss the unusual square dome and thin, elaborate spire of this Turin landmark above the city's rooftops. This odd structure, built between 1863 and 1889, was intended to be a synagogue, but costs escalated and eventually it was bought by the city; it now houses the Museo Nazionale del Cinema (National Cinema Museum), a worthy sight for film buffs. At scheduled times on weekends, you can walk all the way up to the top of the dome, a journey not for the faint of heart (and not permitted for children under age six).
