Prague is one of Europe's most popular tourist destinations. Prague was one of the few European cities relatively untouched during the World Wars, allowing its historic architecture to stay true to form. There are lots of old buildings, many with beautiful murals on them. It also has a lively nightlife, mostly due to the extraordinary range of beers available. It contains one of the world's most pristine and varied collections of architecture, from Art Nouveau to Baroque, Renaissance, Cubist, Gothic, Neo-Classical and ultra-modern. Some of the most known sights are: Malá Strana (Lesser Quarter), Prague, Old Town (Staré Město) with its old town square and the Astronomical Clock. The picturesque Charles Bridge connecting to New Town and Wenceslas square.
Prague Castle is the largest castle in the world with its St. Vitus Cathedral. Also visit the Josefov (the old Jewish quarter) with Old Jewish Cemetery and Old New Synagogue, The Lennon Wall and the several museums such as the museum of Heydrich assassination in the crypt of the Church of Saints Cyril and Methodius and National Museum. Petřínská rozhledna has an observation tower on Petřín hill, which is nearly a 1:5 copy of the Eiffel Tower and another observation deck can be found at Žižkov Television Tower.
