The Penny Bridge, also known as the Ha’penny Bridge or the Liffey Bridge, is a famous pedestrian bridge in Dublin, Ireland. It crosses the River Liffey and connects Ormond Quay Lower to Wellington Quay.

It was built in 1816 from cast iron and was originally named after the Duke of Wellington, who was born in Dublin. The bridge got its nickname from the ha’penny toll that was charged to cross it until 1919. Today, the bridge is a popular landmark and a symbol of the city.
