Budapest Audioguides

Budapest was three cities before it was one. Buda, on the hilly west bank of the Danube, and Pest, on the flat east bank, merged with the ancient settlement of Obuda in 1873 to form a capital that immediately set about building at imperial scale. The Hungarian Parliament Building was completed in 1904 as the third-largest parliament in the world. Andrassy Avenue, a UNESCO World Heritage Site, runs from the center to Heroes' Square, and beneath it runs the M1 line, Europe's first underground railway, opened in 1896 and still operating on the original tracks with period carriages.

What makes Budapest physically unusual is its geology.

The Buda hills sit on 125 thermal springs producing 70 million liters of geothermal water daily, some reaching 58 degrees Celsius. The Ottomans, who occupied the city for 150 years from 1541, built bathhouses over these springs that still operate: Rudas Baths and Kiraly Baths have been running since the 16th century. Romans established Aquincum on the same geology in the first century AD. The baths are not a tourist attraction grafted onto the city; they are genuinely how people spend Sunday mornings here.
