Prague is the capital of Czechia, the "fairy-tale city" on the Vltava River, renowned for its medieval architecture, red-roofed houses, and romantic ambience; the entire old town is a UNESCO World Heritage site. Key attractions: Prague Castle (the largest ancient castle complex in the world, with stunning stained glass at St. Vitus Cathedral), Charles Bridge (a gallery of Baroque statues, most beautiful in the early morning with few people), Old Town Square (the Astronomical Clock chimes every hour, the Gothic twin spires of Týn Church stand out); a Vltava River cruise and Petřín Lookout Tower (mini Eiffel Tower) are romantic must-dos. Local cuisine features traditional Czech home-style dishes; must-tries include roast pork knuckle, beef goulash in beer, potato dumplings, and cinnamon rolls, paired with local Pilsner beer, rich and satisfying.
