2015:449 - DUBLIN: Exchange Facility, Mayor Street, IFSC, Dublin

A programme of monitoring of ground reduction works associated with the construction of an office development at the Dublin Exchange Facility, Mayor Street, I.F.S.C, Dublin 1 was undertaken in compliance with the Grant of Planning issued by Dublin City Council. The general bulk excavations across the site resulted in the removal of rubble fills, largely associated with land reclamation and modern building activities. The deepest excavations, associated with underpinning works, indicated that all such fills sealed a basal layer of silty-sand, presumably formed by river action when the area formed part of the Liffey Flood Plain, and this overlay grey-blue stony marl. No subsurface features of archaeological interest were recovered. However, 47 pottery sherds were retrieved, including 20 of medieval date, from the basal fill-layer of stony clay and the underlying ‘river’ sands, with the remainder dating from the 17th–20th centuries dispersed randomly throughout the upper fill-layers.
