The Castle of Dublin was for a long time the symbol of the reign of England in Ireland. In fact it served this function for almost 700 years, until 1922. The castle was built on order of King John (from Robin Hood) and it quickly turned into a castle for the leaders of the city and country. The castle was often attacked, but tourists can today enjoy everything that is left as they walk inside and outside the buildings in the castle area.
To walk around in the Dublin Castle is free, but some places require an admission fee to be paid. Among the sites worth visiting we recommend: the Chester Beatty Library, the Viking Crypt, the nice park inside the castle area, the Bedford tower, the Record Tower (the sole surviving tower of the medieval castle dating from 1228) and the Royal Chapel.
