Wedge tombs, so called because their burial galleries taper in both height and width from front to back, were typically built during the late Neolithic and into the early Bronze Age, roughly between 2500 and 2000 BC. Clare has an unusually dense concentration of them, and Ballyogan represents one entry in that quietly remarkable county-wide inventory.

The primary record for this monument draws on the fieldwork of Ruaidhrí de Valera and Seán Ó Nualláin, whose Survey of the Megalithic Tombs of Ireland, Volume I, covering County Clare, was published by the Stationery Office in Dublin in 1961. That survey remains a foundational document for understanding the distribution and condition of megalithic structures across the county. De Valera in particular dedicated much of his career to cataloguing these monuments at a time when systematic field survey of prehistoric sites in Ireland was still in its early stages. The work they produced gave researchers and curious visitors alike a baseline from which to understand what had survived, and what had not.
