Dergmore is a Neolithic portal tomb located near Magherafelt in County Londonderry, Northern Ireland. The monument consists of a substantial megalithic chamber constructed from large stone slabs, typical of portal tombs built during the Neolithic period, likely between 3500 and 3000 BCE. The site represents an important example of early monumental burial architecture in the region, reflecting the ritual and social practices of Ireland's earliest farming communities.
