Széchenyi lánchíd or Szechenyi Chain Bridge is a suspension bridge that spans the River Danube between Buda and Pest, the western and eastern sides of Budapest, the capital of Hungary. It was the first permanent bridge across the Danube in Budapest, and was opened in 1849. The bridge had an enormous significance in the country's economics and life. Its decorations made of cast iron, and its construction, radiating calm dignity and balance, raised it among the most beautiful industrial monuments in Europe. It became a symbol of advancement, national awakening, and the linkage between East and West.
Buda Castle is the historical castle of the Hungarian kings in Budapest, Hungary, first completed in 1265. In the past, it was also called Royal Palace. Buda Castle was built on the southern tip of Castle Hill, next to the old Castle District, which is famous for its medieval, Baroque and 19th century houses and public buildings. It is linked to Adam Clark Square and the Szechenyi Chain Bridge.
