Possible long barrow within Valley Plantation at Thorganby. The density of vegetation on the mound precludes any thorough survey being made, therefore this is only tenuously identified as a long barrow. The mound is aligned east to west. The west end had a steep terminal and the east end stops at a hedge line. {1}{2}{3} The site of a possible long barrow next to Thorganby Hall, first reported in 1949. The site was recorded as mutilated and overgrown. The area is now occupied by a small plantation of pines. Its situation is not typical of long barrows in the Wolds. An earthwork survey was carried out by Sheffield University in 1987 but there was no other work carried out. Its interpretation as a long barrow was uncertain, and an alternative origin as an ornamental feature relating to the Hall was also thought possible. {4} The monument includes the substantial and well preserved earthwork and buried remains of a long barrow on the eastern bank of the Waithe Beck, in the heavy woodland of valley plantation about 200m west of Thorganby Hall. The barrow mound is approximately 35m long and 23m wide, standing to a maximum height of 4m at the western end which terminates steeply. The eastern tail of the barrow changes axis in a southerly direction. The ditch from which material for the mound would have been quarried is not visible but it will survive beneath the present ground surface. It is undisturbed by agricultural and archaeological activity. This and other nearby monuments are thought to form a group associated with the valley of the Waithe Beck. The fence and fence-posts are excluded from the scheduling, although the ground beneath them is included. It includes a 10m boundary around the archaeological features, considered to be essential for the monument's support and preservation. For full details see the scheduling documentation. {5} This long barrow, within Valley Plantation, appears to have been incorporated into a medieval lynchet, which may have distorted its shape slightly. Much of the lynchet has been levelled since the 1940s, possibly leaving a remnant on the north slope of the barrow. The site also appears to have undergone several phases of tree planting and felling since at least the 1960s which will have impacted to some degree on the earthwork remains. The barrow survives as an elongated oval mound, aligned roughly west to east, measuring 32m by 10m. The mound has a moderately rounded top with a shallow slope, approximately 0.75m high on the southern side. The steep northern slope drops steeply for a distance of about 3m, at a much sharper angle than the slope to the south. The slope from the west end of the mound down to the beck is also quite steep. {6}
