English: The Széchenyi Chain Bridge is a suspension bridge that spans the Danube River 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.

It is anchored on the Pest side of the river to Széchenyi Square, and on the Buda side to Adam Clark Square, near the Zero Kilometer Stone and the lower end of the Castle Hill Funicular, leading to Buda Castle.

At the time of its construction, it was regarded as one of the modern world's engineering wonders. It has asserted an enormous significance in the country's economic, social and cultural life, much as the Brooklyn Bridge has in New York and America. Its decorations made of cast iron, and its construction, radiating calm dignity and balance, have elevated the Chain Bridge to a high stature in Europe. It became a symbol of advancement, national awakening, and the linkage between East and West.
