houses built on a bridge

Erfurt (Thüringen), Germany

Probably the most famous sight in Erfurt is what you see on the right-hand side of this picture - the 15th century Krämerbrücke (grocers' bridge) - 32 half-timbered houses and shops built on a bridge over a river.  This bridge was originally built out of wood in the 12th century and contained several stands selling food and other miscellaneous items.  Because of numerous fires over the centuries, the bridge was rebuilt out of stone with buildings instsead of stands.  The funny looking wooden structure on the left is a multi-dwelling bird house!
