In light of its location in the very heart of Europe, not to mention its political history, it’s miraculous that Prague emerged from its history so nearly unscathed. For chief among its glories is the beauty of its buildings: its medieval cathedral and the surrounding Castle district, and the gorgeous Baroque streets of Malá Strana on the west bank of the river Vltava. (No wonder Milos Forman opted to shoot Amadeus here.) If this is the Prague that captivates you, try to catch a performance of Mozart’s Don Giovanni at the exquisite 18th-century Estates Theatre, the auditorium for which it was commissioned and where it’s almost invariably in repertory. But 20th-century Prague—where architectural landmarks run from Art Nouveau to Frank Gehry—is fascinating, too, with its supreme examples of Modernism (Adolf Loos’ Muller Villa is the prime exhibit), Cubism (check out the House of the Black Madonna) and Functionalism (the Veletrzni Palac, which also happens to house an outstanding collection of French art).
