Fodor's Expert Review Kostel Nejsvětějšího Srdce Páně

If you've had your fill of Romanesque, Gothic, and baroque, this church offers a startlingly modernist alternative. Designed in 1927 by Slovenian architect Jože Plečnik—the same architect who updated Prague Castle and who almost single-handedly designed the modern city of Ljubljana—the art deco edifice of this church resembles a luxury ocean liner more than a place of worship, topped by a tower with an enormous glazed clock. The effect was purposeful, as during the 1920s and 1930s the avant-garde imitated mammoth objects of modern technology. The interior decor is equally striking, particularly the altar, overlooked by a 10-foot-high gilded figure of Christ, flanked by six Czech patron saints. It's hard to miss the structure, which looms as you exit the Metro.

While the front door (with a view of the interior) is open 9 to 5 every day, entrance is allowed only 45 minutes before and after mass.
