Hlavne Namestie is the main square in Bratislava, Slovakia. It is located in the center of the city in the Old Town. Throughout the year, vendors sell crafts and other souvenirs in the square, and during the Christmas season, this is the place to come for the city's Christmas markets. Other festivals, concerts, and outdoor events are also held in the main square. One of the most significant buildings on the square is the Old Town Hall. Though refurbished, it has been in use since 1434, and you can still see the preserved underpass that was built in 1442 to allow people to enter the building from the square.Visitors can also see a line on the Town Hall building marking the water level of the Danube River during terrible flooding in February 1850. The Bratislava City Museum has an exhibition of the history of the city inside the Old Town Hall building. The main square charms visitors with its Renaissance-style fountain and many outdoor cafes.
