Drumanagh

Drumanagh (Irish: Droim Meánach) 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.

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. 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.
