Drumanagh (Irish: Droim Meánach)[1] is a headland near the village of Loughshinny, in the north east of County Dublin, Ireland. It features an early 19th-century Martello tower and a large (200,000 m²) Iron Age promontory fort which has produced Roman artefacts.
Some archaeologists have suggested the fort was a bridgehead for Roman military campaigns, while others suggest it was a Roman trading colony, or at least the site of a regular trading "fair", or a native Irish settlement that traded with Roman Britain, as Roman brooches and metalware in the style of Roman Britain were found nearby.[2][3]
The site was acquired, reportedly for about €1 million, by Fingal County Council in 2017. In early 2018 they announced a Draft Conservation and Management Plan for consultation, including protection from further damage by motorbike scrambling, and integration into coastal walking paths.[4] The purchase has raised hopes that the site will finally receive proper archaeological investigation, which will answer many of the questions that have been the subject of speculation for decades.[5]
