Víziváros

Watertown is the narrow area between the Danube and Castle Hill that widens as it approaches Óbuda to the north and Rózsadomb (Rose Hill) to the northwest, spreading as far west as Moszkva tér, one of Buda's main transport hubs. Under the Turks many of the district's churches were used as mosques, and baths were built, one of which is still functioning. Víziváros begins at Clark Ádám tér, leading east from the square.

The street was named after the 19th-century Scottish engineer who supervised the building of the Széchenyi Chain Bridge (Széchenyi lánchíd). Clark also designed the all-important tunnel (alagút) under Castle Hill, which took eight months to carve out of the limestone. The curious sculpture, which looks like a elongated doughnut, hidden in the bushes to the south is the 0km stone; all Hungarian roads to and from the capital are measured from this exact spot.
