Clark Adam Square Budapest, Hungary

Adam Clark was the British engineer who built the first permanent bridge, Lanc Hid or Chain Bridge, over the Danube in the 1840's. In his honour, the square (actually a fiendishly busy traffic roundabout) was permanently named after him. It stands at the end of the bridge on the Buda side, just before the tunnel (also built by Adam Clark) under the castle. This bridge - like all the bridges - was blown up by the retreating Germans during the Second World War, but has since been reconstructed, along with the others.
