If you've had your fill of Romanesque, Gothic, and baroque, this church will give you a look at a startling modernist art deco edifice. Designed in 1927 by Slovenian architect Josip Plečnik (the same architect commissioned to update Prague Castle), the church resembles a luxury ocean liner more than a place of worship. The effect was purposeful, as during the 1920s and 1930s the avant-garde imitated mammoth objects of modern technology. Plečnik used many modern elements on the inside. You may be able to find someone at the back entrance of the church who will let you walk up the long ramp into the fascinating glass clock tower. It's hard to miss the structure, which looms as you exit the metro.
