This is the postcard shot you always see - the world's most humongous Gothic castle. Don't leave Prague without it.
There is absolutely no way you can possibly leave town without climbing up to the Hradčany district to visit the Pražský Hrad, this city's great symbol, and considered the world's largest Gothic castle, 570 metres (1,870 feet) long and 130 metres (427 feet) wide. Dating back to the 9th century, it was the residence of the kings of Bohemia, Holy Roman Emperors, Habsburg emperors, rulers of Czechoslovakia under democracy, Naziism, and Communism, and now the presidents of the Czech Republic. In its interior you'll find, in addition to the crown jewels of Bohemia, St. Vitus Cathedral, St. George's Convent (where you can enjoy some wonderful antique Bohemian artwork), the Old Royal Palace, and galleries of Baroque and Renaissance art, among much else. The Prague Castle was renovated between 1920 and 1934 by architect Jože Plečnik at the behest of the first president of Czechoslovakia, Tomáš Masaryk, whose statue you will also find inside.
