Some of the Sights and location for which Dublin is famous for are as follows
Dublin Castle: Dublin Castle is more correctly described as a palace. The most fascinating part of the castle is underground - a chunk of the old city walls and moat.
National Museum of Ireland: Among this rich collection of Irish antiquities, are the eighth-century Ardagh Chalice and Tara Brooch and the 12th-century Cross of Cong.
Christ Church Cathedral: Richard de Clare 'Strongbow' founded Christ Church Cathedral on the site of a Viking church in 1172. Highlights include the 'leaning wall of Dublin', a mummified cat and mouse found in an organ pipe, the heart of St Laurence, the patron saint of Dublin, and a large crypt full of unusual relics.
