The O'Cornell Monument was built in memory of Daniel O'Cornell, the 19th century Irish national leader, and the street was named after him. The O'Connell Bridge across the Liffey River opposite the O'Connell Monument is naturally named after him. The bridge links O'Cornell Avenue with D&39; Olier Avenue and docks. It was built in 1794 and named O'Cornell Bridge in 1880. When we went, the streets and bridges were under renovation and construction, so they looked so messy that the whole picture of the bridge could not be seen clearly. The middle part of the second and third pictures was the middle of the bridge deck. The fourth and fifth pictures were taken on the two sides of the bridge, the Lifei River and the distant bridge.
