Bratislava is the capital that most people see from a train window on the way to somewhere else. It deserves more. For almost three centuries, from 1563 to 1830, Hungarian kings and queens were crowned here, in St. Martin's Cathedral, and the city was the capital of the Kingdom of Hungary for much of that time. Then came the Habsburgs, Czechoslovakia, four Communist decades of concrete and a border fence, and, since 1993, a small independent capital that sits about 60 km from Vienna and borders both Austria and Hungary.
It's a compact place and an honest one. The old town is a few streets of pastel facades and statues in the road, the castle is a white box on a hill, and the most photographed building is a flying saucer on a bridge. Nothing here needs a whole week, but three days lets you do it without hurrying: one day for the Old Town and the castle, one for the Devín ruin, the Blue Church and the views, and one for a day trip into the Small Carpathian wine country, which is the better use of a third day than a second lap of the same cobbles.
The plan is built around the opening days. Start on a Wednesday: the castle exhibitions are closed on Tuesdays, Devín is closed on Mondays, and the museums on day three are open Tuesday to Friday and shut on Sundays in winter. Day one is the Old Town and the castle, day two is Devín and the city's blue, white and concrete landmarks, day three is Pezinok and Modra. It's also a good gateway to Slovakia as a whole, and from here the mountains are a long train ride away, as the Jasná ski guide shows.
