I thought it was a historic site, but it turned out to be a very ordinary bridge. It just has some historical allusions. This bridge was the only pedestrian bridge that could cross the River Liffey at that time. In 1816, in order to connect the north and south urban areas of Dublin, the Irish built a beautiful light bridge over the river for pedestrians only. When the bridge was built, pedestrians were required to pay a half-penny toll on the notice, so it was called the "Halfpenny Bridge".
