O'Connell Street and O'Connell bridge across the river Liffey are named after Daniel O'Connell, polictician and liberator and Ireland's political leader in the first half of the 19th century. He campaigned the rights for Catholics to sit in the Westminster Parliament.
Daniel O'Connell's statue stands close to the bridge. The angels at the base of the monument represent Ulster, Munster, Leinster and Connought, the four Irish provinces.
You may notice that O'Connell bridge has strange proportions; it is wider than it is long. It was not designed this way but was widened two years after it had been built. A foresight, especially in view of today's traffic.
