This small island holds thousands of years of human history within its shores. While the island itself is natural, archaeological evidence suggests it was modified over time, including the construction of a landing quay that would have made access easier for its various inhabitants throughout the centuries.

Excavations carried out by Davies in 1946 revealed a fascinating timeline of occupation spanning from the Neolithic period right through to post-medieval times. The dig uncovered an impressive array of artefacts: Neolithic flintwork tells us of the island’s earliest visitors, whilst pottery fragments from more recent centuries show continued use well into the post-medieval period. However, the bulk of the finds date to the medieval period, suggesting this was when the island saw its most intensive use, possibly as a crannog; a type of fortified dwelling built on islands or artificial platforms that were particularly popular in Ireland during medieval times.

The strategic location of Inishgarve would have made it an attractive spot for settlement and defence. Islands like this one served multiple purposes throughout Irish history; they could function as secure homesteads, places of refuge during times of conflict, or centres of local power. The presence of a constructed quay indicates this wasn’t just a temporary refuge but a place where people lived, worked, and maintained connections with the mainland communities around Lough Eske.
