The Custom House (Irish: Teach an Chustaim) is a neoclassical 18th century building in Dublin, Ireland which houses the Department of Housing, Planning and Local Government. It is located on the north bank of the River Liffey, on Custom House Quay. The building of a new Custom House for Dublin was the idea of John Beresford, who became first commissioner of revenue for Ireland in 1780. In 1781 he appointed James Gandon as architect, after Thomas Cooley, the original architect on the project, had died. (wikipedia.org)
