Take the afternoon to stroll around the beautiful city of Dublin as well as maybe doing a bit of shopping up Grafton Street. In the evening go to one of the many lovely Irish pubs in Temple Bar or even Temple Bar itself.
The Guinness Storehouse is a must see while you are in Dublin. Not only do you learn about the history of Guinness and how it is made you also get to have a pint (which is included with your ticket) at the top of the Storehouse which gives you such a good view of Dublin!
This building is part of the factory, it was built in 1902. The atrium of the museum is made in the form of a pint beer glass, which theoretically can accommodate 14.3 million pints of beer. Incredible!
The book of Kells are located in the centre of Dublin and takes you back to the 18th Century when the old library was constructed and which displays the Book of Kells.
The Book of Kells is Ireland's greatest cultural treasure and the world's most famous medieval manuscript. The 9th century book is a richly decorated copy of the four Gospels of the life of Jesus Christ.
While you are there take a walk around the grounds of Trinity College Dublin too.
While visiting the little museum of Dublin. Have a walk around St Stephen's Green which the museum is right next to if it is a nice day. The current landscape of the park was designed by William Sheppard in 1664. St Stephen's Green fountain in summer is so beautiful.
St Patrick's Cathedral is the tallest and largest church in Ireland. Built between 1220 and 1260, St Patrick's Cathedral offers visitors a cultural experience and is one of the few buildings left of medieval Dublin. While you are also in the area take a trip to Christ church Cathedral.
A full Irish breakfast is a very hearty breakfast similar to the English breakfast but with black or white pudding and sometimes with some Irish soda bread. A must have before a journey home.
