The city of Budapest, Hungary, the seat of national government, was formed by merging the cities of Buda on the left bank of the Danube River and Pest on the right bank. The sights of the city reflect its 1,000 year history, including being part of the former Austro-Hungarian Empire, which disintegrated after the World War. This fact is illustrated by a floral map and flag at half mast in Liberty Square. Some of the main sights in the city are the Store House of the Hungarian Archives, the Széchenyi Chain Bridge completed in 1849, the Royal Palace, Coronation Church (which is only one of several monuments in the city associated with Saint Stephen), the Museum of Agriculture, and the thermal grotto on Margaret's Island which is known for its many spring fed swimming pools. Rivalling any in Europe, it is a cosmopolitan city, whose culture is punctuated by the music of Franz Liszt.
