The Széchenyi Chain Bridge pans the River Danube between Buda and Pest, the western and eastern sides of Budapest, the capital of Hungary. Designed by English engineer William Tierney Clark and built by Scottish engineer Adam Clark. It was the first permanent bridge across the Danube in Hungary. It was opened in 1849. The bridge has the name of István Széchenyi, a major supporter of its construction, attached to it, but is most commonly known as the "Chain Bridge". At the time of its construction, it was regarded as one of the modern world's engineering wonders. 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.
