The historic bridge over the Ocna River was built in 1859, which makes it the oldest iron bridge in Romania. It was also the second bridge of this type built in Europe. It connects Piața Mică Square in the Lower Town with Piața Mică Square in the Upper Town.
The bridge is 10.40 m long and consists of 8 panels decorated with Gothic elements. On one of the arches there is the coat of arms of the city, and on another the date of construction of the bridge and the name of the foundry, which supplied some of the materials.
Initially, the bridge was called Liegenbrücke, meaning Lying Bridge. It sounded similar to Lügenbrücke, or Lie Bridge, and it was this name that quickly adopted. Several urban legends are associated with it. According to one on the bridge, cadets from the Military Academy met with their chosen ones. They promised lifelong love, after which many of them never returned to the city. According to another version, dishonest merchants were thrown from the bridge who cheated during fairs taking place on the nearby square.
