Tumulus de la Hogue, Neolithic burial mound in Fontenay-le-Marmion, France

Tumulus de la Hogue is an oval Neolithic mound 49 metres long north to south and 37 metres wide east to west, built on Jurassic limestone in the Caen plain. Its north-west quarter was removed by stone quarrying, leaving the eastern face best preserved. Inside are twelve sub-circular dry-stone burial chambers reached by radiating passages, roofed by corbelling; chamber A, 3.80 metres across, has small limestone slabs set on edge as internal partitions.

The site was found in 1829 by workers quarrying stone for communal roads. Excavations led by Arcisse de Caumont for the Société des antiquaires de Normandie followed in 1830–1831, and stone was again removed in 1834–1835. The owner of the Château de Fontenay, M. Le Hardelay, bought the mound in 1840 to save it from destruction. It was classified as a monument historique on 26 December 1905.

The name is redundant: in Old Norman, hogue meant "hill" or "mound", from Old Norse haugr, a word that also denoted a sacrificial hill or cairn. Local tradition held the mound was a Roman cemetery, where a general was buried under stones carried by his soldiers; Léon Coutil recorded this legend in 1902.

The site is located in Normandy in the Calvados department and remains protected as a historical monument. Visitors should wear sturdy shoes as the ground is uneven and entering the stone chambers requires careful footing.

Local tradition held that a Roman general killed in battle on the plains of May and Fontenay was buried here, each soldier adding a stone to the mound. Excavations in the 19th century disproved the belief in a treasure hidden beneath it.
