US President Joe Biden arrives at Dublin Castle, the ancient seat of English and then British authority in Ireland, to attend a banquet being held in his honour on the second day of his visit to the country. Biden's trip comes on the 25th anniversary of the Good Friday Agreement. Before the banquet, the US President -- one who has frequently expressed pride at his Irish roots -- delivered a speech to the Irish Parliament, in which he hailed the ties between Ireland and the United States.
