The Chain Bridge (Széchenyi Lánchíd) is the first permanent bridge to connect the two parts of Budapest (Buda and Pest). The bridge was designed by William Tierney Clark and the lions were sculpted by János Marschalkó, and legend has it that after discovering he forgot to put his tongue in the lions mouth he jumped into the Danube water. This is just a legend, since János Marschalkó passed away 25 years after finishing the lion statues.
