Here is some info on the city: Bratislava — historically Pozsony and Pressburg — is the capital of the Slovac Republic and, with a population of about 429,000, also the country's largest city. Bratislava is in southwestern Slovakia on both banks of the Danube River. Most historical buildings are concentrated in the Old Town. Notable cathedrals and churches include the gothic St. Martin's Cathedral built in the 13th–16th centuries, which served as the coronation church of the Kingdom of Hungary between 1563 and 1830. (we can see it to the right on the card)
The square castle on the card is "Bratislava Castle, on a plateau 85 metres (279 ft) above the Danube. The castle hill site has been inhabited since the transition period between the Stone and Bronze ages and has been the acropolis of a Celtic town, part of the Roman Limes Romanus, a huge Slavic fortified settlement, and a political, military and religious centre for Great Moravia. A stone castle was not constructed until the 10th century, when the area was part of the Kingdom of Hungary. The castle was rebuilt in 1649 in the baroque style. Under Queen Maria Theresa, the castle became a prestigious royal seat. In 1811, the castle was inadvertently destroyed and lay in ruins until the 1950s, when it was rebuilt mostly in its former Theresan style."
