2003:520 - DUBLIN: River Liffey, Custom House Quay/City Quay, Dublin

An underwater archaeological and metal-detector survey of the River Liffey took place along a corridor between Custom House Quay and City Quay just west of Lombard Street, Docklands, Co. Dublin. A detailed record of the quay wall and survey of associated areas of riverbed was carried out as part of the archaeological requirement for the planning application associated with the development of this site.

The riverbed in this area has been subjected to a cycle of dredging and redeposition of silts at regular intervals. Dumping of modern debris from both the quayside and from the vessels using this area also contributes to the nature of materials in this area. Near continuous metal detector readings were encountered along an approximately 5m-wide zone adjacent to the quaysides, with metal detector readings occurring approximately every 1.5m elsewhere. All of the identified materials were modern debris.
