The Hradecky Bridge is one of the first hinged bridges in the world, the first the only preserved cast iron bridge in Slovenia, and one of its most highly valued technical achievements. It has been situated on an extension of Hren Street (), between the Krakovo Embankment () and the Gruden Embankment (), connecting the Trnovo District and the Prule neighbourhood in the Center District. The Hradecky Bridge was manufactured according to the plans of the senior engineer Johann Hermann from Vienna in the Auersperg iron foundry in Dvor near Žužemberk, and installed in Ljubljana in 1867, at the location of today's Cobblers' Bridge.
