The World Heritage site consists of the area on the Buda side between the buildings of the University of Technology and the Lánchíd (Chain bridge), including the Gellért spa baths, the Freedom Statute (Szabadság szobor) and the Citadel (Citadella) on Gellért Hill, and the buildings of the Buda Castle.

On the Pest side the area includes the Parliament building, Roosevelt tér at the Pest end of the Lánchíd, together with the Hungarian Academy of Science (Magyar Tudományos Akadémia) and the Gresham palace. The four bridges over the Danube in this area are also a part of the World Heritage site. 

Following this, the Fisherman's Bastion was built in the neo-Romanesque style on the medieval castle walls. Opposite, on the Pest side stands one of the world's most beautiful parliament buildings. With its length of 268 metres and 96 metre high dome it provides an imposing sight above the waves of the Danube. lt may be visited in groups, and it is worth visiting not only for the beautiful interiors, the shining golden decorations, the frescos and statues made by the famous artists of the ago and the decorated stairways, but also to see the 1000 year old crown of the first Hungarian king, saint Stephen.

The first stone bridge built here over the Danube, the Lánchíd, has become a symbol of the city. The Széchenyi Chain Bridge is a chain suspension bridge incorporating architectural elements in the classicist style. This was the first fixed stone bridge over the Danube in the capital. After Széchenyi's initiative it was constructed from 1839 to 1849. The englishman William Thierney was its designing architect. It was carried out by another englishman, Adam Clark, who later on settled in the city. Count István Széchenyi, often called '”the greatest Hungarian” initiated the foundation of the Hungarian Academy of Science, enhanced steamship transport on the Danube and paid the costs of the buildíng of the first permanent bridge between Pest and Buda (Chain Bridge, Lánchíd) was also Minister of Transport in 1848 in the first independent Hungarian government. His old castle in Nagycenk has been turned into a museum.
