To visit Bratislava, the capital of Slovakia, is to discover a small capital on the Danube, a few dozen kilometers from Vienna: a four-towered castle above the river, an old town where the kings of Hungary were crowned, an Art Nouveau Blue Church and the ruins of Devín. What to see in Bratislava, how to plan one or two days and when to go based on World Meteorological Organization normals: here are the essentials, backed by verified sources.
Bratislava has around 475,000 inhabitants (2020). In the southwest of the country, it borders both Austria and Hungary. Before 1919 it was called Pressburg in German and Pozsony in Hungarian. Between 1536 and 1830, it was the coronation city of the kings and queens of Hungary.

What to see in Bratislava: the top sights
Bratislava Castle
Set on a plateau 85 m (279 ft) above the Danube, the castle with its four corner towers is the symbol of the city; it appears on the Slovak 10, 20 and 50 euro-cent coins. The site has been occupied since prehistoric times. The stone castle, begun in the 10th century, became a Gothic fortress in 1430, then a Renaissance and later Baroque castle, and a royal residence under Maria Theresa. Burned in 1811, it stayed in ruins until its reconstruction from the 1950s-1960s. Today it houses a history museum of the Slovak National Museum. From its grounds, the view takes in the city, Austria and, on clear days, Hungary.
St Martin’s Cathedral
Below the castle, the Gothic St Martin’s Cathedral was built from the 13th to the 16th century. It served as the coronation church of the Kingdom of Hungary from 1536 to 1830.
The old town and St Michael’s Gate
Most of the historic monuments are in the old town. The Old Town Hall, a group of three 14th- and 15th-century buildings, houses the Bratislava City Museum. St Michael’s Gate is the only surviving gate of the medieval fortifications; the narrowest house in Europe is close by. The center also has many Baroque palaces: Grassalkovich Palace, from around 1760, is the residence of the president, and the Primate’s Palace is where the Treaty of Pressburg was signed in 1805, after Napoleon’s victory at Austerlitz.
The Blue Church
The Church of St Elizabeth, nicknamed the Blue Church for its color, is built entirely in the Hungarian Secession style, the Hungarian variant of Art Nouveau. It lies east of the old town, a short walk away.
The SNP Bridge and its « UFO » tower
The Bridge of the Slovak National Uprising (Most SNP) crosses the Danube and carries a restaurant tower shaped like a flying saucer at its top. It is one of the landmarks of the skyline, along with the Kamzík TV tower, which has an observation deck.
Devín Castle
West of the city, the ruins of Devín Castle overlook the confluence of the Morava, which forms the border with Austria, and the Danube. An important fortress of Great Moravia, destroyed by Napoleon’s troops in 1809, it is one of the country’s main archaeological sites and a symbol of Slovak history. It houses a museum. Sightseeing boats run from Bratislava’s port to Devín.
Museums and Danubiana
The Slovak National Museum, on the old-town embankment, is the country’s largest cultural institution. The Slovak National Gallery occupies the Esterházy Palace and the former water barracks (Vodné kasárne) by the Danube. Further south, near the Čunovo waterworks, the Danubiana art museum is one of the newest in Europe. Check opening hours and closing days before your visit.

Day trip from Vienna or stop on a tour?
Trains and buses link Bratislava with Vienna, and the A6 motorway has connected the two capitals since 2007. Bratislava is therefore easy to visit on a day trip from Vienna. It also fits into a Central European tour with Budapest and Prague: the city is a rail hub with direct connections to Austria, Hungary and the Czech Republic. Check timetables on the rail operators’ websites.
