Michelle Obama has arrived in Ireland for a 24-hour visit while the G8 summit takes place.
The US First Lady flew into Dublin Airport with daughters Malia, 14, and Sasha, 12, after her appearance in Belfast, before travelling to Trinity College to learn more about the family's Irish heritage and ancestry.
The Obamas will later enjoy a special performance of Riverdance at the Gaiety Theatre before spending the night at the Shelbourne Hotel, followed by a trip to the Wicklow Mountains national park on Tuesday morning.
At Trinity, the Obamas visited the Old Library and were shown the Book of Kells, a ninth-century, elaborately decorated gospel manuscript made by Irish monks.
Mrs Obama, Malia and Sasha were also shown the birth registry of President Obama's Irish ancestors from around the village of Moneygall and old maps detailing the family's homestead in Co Offaly.
Dressed casually in jeans and jackets, the girls listened carefully and chatted to tour guides as they happily strolled the length of the Long Room in the famous Old Library of Trinity - Ireland's oldest university.
