No trip to Dublin would be complete without passing through O’Connell Street. 150 feet wide, it’s Dublin’s equivalent of Oxford or Parliament Street. Once known as Sackville Street and topped with statue of Nelson, it was renamed after the Irish Free State established itself and now has a monument to Daniel O’Connell at one end and “the spire” – the world’s tallest piece of sculpture – at the other. While you’re there, visit the neoclassical grandeur of The Custom House or an older seat of government, Dublin Castle, the garden of which lies on the historical Black Pool (Dubh Linn) the site Ireland’s capital is named after.
