Budapest later, with the help of the Russian Empire. 1867 was the year of Reconciliation that brought about the birth of Austria-Hungary. This made Budapest the twin capital of a dual monarchy. It was this compromise which opened the second great phase of development in the history of Budapest, lasting until World War I. In 1849 the Chain Bridge linking Buda with Pest was opened as the first permanent bridge across the Danube and in 1873 Buda and Pest were officially merged with the third part, Óbuda (Old Buda), thus creating the new metropolis of Budapest. The dynamic Pest grew into
Budapest the city. Special vehicles in Budapest, besides metros, include suburban rails, trams and boats. There are a couple of less common vehicles in Budapest, like the trolleybus on several lines in Pest, the Castle Hill Funicular between the Chain Bridge and Buda Castle, the cyclecar for rent in Margaret Island, the chairlift, the Budapest Cog-wheel Railway and children's railway. The latter three vehicles run among Buda hills. The culture of Budapest is reflected by Budapest's size and variety. Most Hungarian cultural movements first emerged in the city. Budapest is an important center for music, film, theatre, dance and visual art.
