This twin-towered span is the oldest and arguably the most beautiful bridge over the Danube. It is named in honour of its initiator, István Széchenyi, but was built by a Scotsman named Adam Clark. When it opened in 1849, Széchenyi Chain Bridge was unique for two reasons: it was the first permanent dry link between Buda and Pest, and the aristocracy, previously exempt from all taxation, had to pay the toll.
