Perhaps the most eye-popping piece of 20th-century architecture anywhere, and one of the most impressive modernist churches in France, is the Église St-Joseph, built to the plans of Auguste Perret in the 1950s. The 350-foot tower powers into the sky like a fat rocket. The interior is just as thrilling. No frills here: the 270-foot octagonal lantern soars above the crossing, filled almost to the top with abstract stained glass that hurls colored light over the bare concrete walls. Star Wars had nothing on this!
