From the Castle District theres a nice view of the other river bank, where Pest sits. You can see here the most famous bridge in town: the Chain Bridge. This was the first bridge over the Danube, constructed between 1839 and 1849. The bridge is also known as the Széchenyi bridge (after the Count István Széchenyi). This bridge was destroyed during World War II, and re-opened in 1949.
Behind the bridge you can see St. Stephens Basilica, the biggest in Budapest (with 8,500 seats). Its construction was a rather difficult enterprise: both architects died, the independence war was declared and the dome collapsed during the time it was being built .
Well now take a look at the Royal Palace from the Citadel ...
