The Chester Beatty Library is situated in the grounds of the historic Dublin Castle, which was the seat of British rule in Ireland until 1922. A castle has stood on the site since the days of King John, the first Lord of Ireland; however, most of the buildings date from the eighteenth century.
The complex of buildings is usually open to the public, except during state functions. Among the areas open for viewing are St Patrick's Hall, a vast ballroom in which state presidential inaugurations take place, the Throne Room, containing a throne from the reign of King William III, and the Viceregal Apartments, which include the rooms once used by the lords lieutenant and visiting members of the British royal family.
Dublin Castle is currently maintained by the Office of Public Works and houses the offices of the Revenue Commissioners.
