The Ha'penny Bridge (Irish: Droichead na Leathphingine, or Droichead na Life), known later for a time as the Penny Ha'penny Bridge, and officially the Liffey Bridge, is a pedestrian bridge built in 1816 over the River Liffey in Dublin, Ireland.[2] Made of cast iron, the bridge was cast at Coalbrookdale in Shropshire, England.[4]

Originally called the Wellington Bridge (after the Duke of Wellington), the name of the bridge changed to Liffey Bridge. The Liffey Bridge (Irish: Droichead na Life)[1] remains the bridge's official name to this day, although it is still commonly referred to as the Ha'penny Bridge. Wikipedia
