Prague, capital city of the Czech Republic (former Czechoslovakia), is bisected by the Vltava River. Nicknamed “the City of a Hundred Spires” it's known for its Old Town Square, the heart of its historic core, with colorful baroque buildings, Gothic churches and the medieval Astronomical Clock, which gives an animated hourly show.  With its gothic exuberance, 19th-century opulence and 20th-century modernism, Prague truly is a city like no other.
