added by archaeologs An Early Neolithic long barrow in Oxfordshire, southern England, with two phases of construction. The earlier monument covered a wooden mortuary house which contained the remains of 14 individuals. Over this was constructed a much longer trapezoidal mound with a stone kerb and with a megalithic chamber of Severn-Cotswold type. A radiocarbon date of ¿2800 be (c3600 bc) was obtained from the surface of buried soil underneath the second-phase monument.
