Arran House Custom House

Built on eleven hectares of former port land, the IFSC transformed derelict docklands into Ireland's financial quarter from 1987 onwards. Gandon's Custom House still presides over the quays, while the restored CHQ warehouse — once the largest interior space in nineteenth-century Dublin — now houses the emigration museum. Modern glass towers and canal-side apartments have created a new residential quarter where container ships once berthed.
