Why it mattered

The source records: The Ballyshannon sewerage scheme involved the monitoring by Giles Dawkes of Archaeological Development Services Ltd under licence No. 07E0620 of a series of machine-excavated trenches in areas identified as having archaeological potential in and around Ballyshannon.
