Long Barrows and Neolithic Elongated Enclosures in Lincolnshire: An Analysis of the Air Photographic Evidence

Abstract

The long barrows of Lincolnshire have been the subject of long-term but intermittent interest. One aspect not investigated hitherto is the air photographic evidence for plough-levelled long barrows. Recently completed mapping work in the county by the Aerial Survey section of the Royal Commission on the Historical Monuments of England (RCHME), as part of the National Mapping Programme, has made possible the analysis of the air photographic evidence. This article presents an evaluation of that evidence and considers its significance in terms of the Neolithic of the region.A comprehensive survey of air photo collections has dramatically increased the number of long barrows known in the county, identifying over 50 examples of levelled sites. The majority are found on the chalk Wolds where the dozen surviving earthwork monuments are located. The distribution of long barrows in the county may now be extended onto the Jurassic Limestone ridge to the west where five examples have been recorded. The Lincolnshire long barrow enclosures have three categories of shape; oval, trapeziform, and oblong. The ditch plan is predominantly full-enclosing, and is found as the distinct form in the eastern region of England. The morphology and dimensions of two sites suggests they may have been a long mortuary enclosure or short cursus.At Harlaxton in the southern Limestone a long barrow enclosure forms part of an extensive later Neolithic ritual complex which incorporates a multiple pit-alignment as a principal component. The form of the complex appears to be unique and underlines the importance of Harlaxton as an inter-regional link.
