In 1987 Budapest was added to the UNESCO World Heritage Site for the cultural and architectural significance of the Banks of the Danube, the Buda Castle Quarter and Andrássy Avenue (map).
Many of Budapest’s highlights are easy to approach walking, and in the centre you find more pedestrian zones from year to year. Don’t wear high-heeled shoes in the centre as there are lots of stone pavements, especially in the Castle Hill.
*Budavár (Buda Castle, Inner part of District I, map). The oldest part of the city containing the Castle and some of Budapest’s best-known attractions such as Fishermen’s Bastion (map), the Labyrinth (map) and Mathias Church (map). All areas are part of the UNESCO World Heritage Site.
*Belváros (Inner City, District V, map). The highlight of this area is the Parlament, the Saint Stephen Basilica (map) and the Promenad (Corso) with beautiful views of the Danube and to the Castle Hill.
*Terézváros (Theresa Town, District VI, map). Historical districts full of monumental buildings, museums, luxury shops along Andrassy Avenue (map). Most theatres and accommodation are here.
You definitely want to visit the Great Market Hall (Nagy Vásárcsarnok, map) at Fővám tér, the renovated market hall with essential atmosphere (it’s at the south end of Vaci). Prices for the same items vary a lot between sellers and aren’t set in stone so be sure to compare and bargain.
The city also has around 80 *geothermal springs, the largest thermal water cave system. One of the reasons the Romans first colonised the area immediately to the west of the River Danube and established their regional capital at Aquincum (now part of Óbuda, in northern Budapest) is so that they could use and enjoy the thermal springs.
