Reasons for Designation

D-Day, June 6th 1944, is one of the most significant dates in modern history, defining the start of the final phase of World War II in Europe. After 2-3 years of preparations, the assault phase of `Operation Overlord' - codenamed Neptune - lasted for little over three weeks and by 30 June had landed over 850,000 men on the invasion beachheads, together with nearly 150,000 vehicles and 570,000 tons of supplies. Sites used for the building, maintenance and repair of landing craft and landing ships were essential to developing and retaining a fleet capable of delivering Prime Minister Churchill's `great plan'. With so many vessels involved (landing craft and landing ships principally, but there were 46 different types in all), construction and maintenance were significant tasks. Contemporary descriptions refer to unprecedented levels of maritime activity, with every port, harbour and boatyard being involved, in addition to beaches and the streets of coastal towns and villages. The more substantial sites were either in largely unmodified dry docks or on specially built `gridirons' or slipways. The gridirons were used for maintenance, and took the form of a series of parallel concrete slipways running down a slight gradient into the water, allowing the boat to be floated on at high tide and repaired at low tide; some were supplied with a winch mechanism for pulling vessels onto the grid, and steel mooring points (`dolphins') for securing them when afloat. Recorded examples include sites on the Rivers Dart (Devon), Tamar and Fal (Cornwall), and in Portsmouth Harbour. Slipways, with a metal rail, winch mechanisms and dolphins, used for landing ship repairs, are recorded on the River Dart. However, much construction, repair and maintenance work was conducted on an ad hoc arrangement and leaves little trace: for example, landing craft (assault) - LCAs - were small vessels constructed and repaired mainly in back streets and improvised hards at the water's edge. Although in military archaeology fixed defences will often survive better than materiel representing the mobile offensive, sufficient of the preparations for D-Day in England remains to give an impression of the scale of the Operation, and the variety of the specific tasks involved. All sites where surviving remains provide an impression of the scale and nature of the preparations for D-Day will be considered of national importance.

The D-Day landing craft maintenance site at Lower Noss Point represents an exception survival with two gridirons retaining all twelve piers, in association with mooring posts and some onshore survival of the maintenance area. The combination of foreshore and onshore facilities with this level of survival is considered to be unique. It was one of several such sites on the River Dart, of which only three remain in anything like their original form. The monument's importance is enhanced by the immediate post-war aerial photographs of the site in its near original state and by valuable recorded detail about the site's location within the wider context of the USNAAB at Dartmouth.

Details

The monument includes a maintenance and repair site built on the east bank of the River Dart upstream from the port of Dartmouth to service landing craft during the preparations, engagement, and aftermath of the 1944 D-Day landings during World War II. The site includes two separate, but closely adjacent, arrangements of concrete piers called `gridirons' plus three earthfast concrete mooring posts and various components of the onshore facility. Operating from 1943 to 1944 the monument was one of a number of repair and maintenance sites on the River Dart which were under the control of the United States Naval Advanced Amphibious Base (USNAAB) at Dartmouth. These repair sites contributed to the preparations for the D-Day invasion of 6th June 1944, codenamed Operation Overlord, and were part of the range of shore-base and supply facilities constructed before and during the invasion. After D-Day, the importance of USNAAB Dartmouth as a base began to wane and the facilities were handed back to the British before the end of 1944. Gridirons were designed to allow flat-bottomed landing craft to be floated over them sideways at high tide and then moored, coming to rest upon the piers of the gridiron as the tide fell and thus enabling inspection, scraping, and repairs to be carried out. The two gridirons at Lower Noss are virtually identical in plan, each being about 54m in width and comprised of 12 parallel straight piers centred 4.85m apart. The piers are just over 30m in length and slope gently down the intertidal shore to just below Mean Low Water (MLW). The downstream gridiron, which lies about 25m south of its upstream companion, has a few piers at its centre which extend back to the rock face and thus exceed the 30m plus length which appears to be standard and which was encountered at another gridiron site at Maypool further upriver. The piers, which are built of shuttered concrete and are embedded in the foreshore shingle and mud, have a maximum width of about 0.7m; excavation of a gridiron site at Mylor in Cornwall suggests that the piers sit upon a concrete raft although this could not be determined at Lower Noss. Along the upper edges of each pier are a series of opposed recesses 0.6m in length by 0.18m wide and 0.12m deep, centred 3.2m apart. These recesses are believed to have held timber rails formerly laid along the piers' upper surfaces at right angles to them perhaps in order to prevent the bottom of the craft's hull from coming into direct contact with the concrete of the piers. The timber and steel mooring points (`dolphins') which would have stood within the river and which would have held the craft whilst afloat and during the positioning process, no longer survive. However, three massive concrete mooring posts, two on the foreshore and one above Mean High Water survive. Each mooring post has a deep central recess which would have held a wooden post all of which have been removed or no longer survive. The two foreshore emplacements are both about 4.5m square at the base and taper towards the top. Both are built into the rock face and stand about 1.9m high, one to the north east of the upstream gridiron about 16m to its rear and the other to the south east of the downstream gridiron about 18m to its rear. The onshore mooring post, unlike those on the foreshore, is almost completely earthfast with only about 0.3m of its structure showing above ground. In other respects it is similar however, being 4.5 sq m with a central recess which would have once held a post. Associated with the gridirons was an onshore facility. Immediately behind the southern end of the upstream gridiron are two flights of concrete steps screened by brick-built walls. These steps give access to a levelled area which,until 2003, housed a building known as a Curved Asbestos Hut of a type often misidentified as a Nissen hut. Prior to demolition the hut was recorded by way of drawn plans and photographs. It was 11.5m long by 5.6m wide and it appears white in an aerial photograph of 1946 taken not long after de-commission which also shows the gridirons at low tide. To the south of the hut was a small brick building, 1.1 sq m and 2m high, also demolished in 2003, which appears to have been a latrine. A sunken stone-lined water tank survives close to the top of the steps. Some collapsed iron racking located to the rear of the hut was recorded in 2002. It consisted of two sets of racking; each set comprising three A-frames supporting two runs of shelving. The whole complex is considered to have represented a workshop or stores area associated with the repair of landing craft on the nearby gridirons. All modern fencing is excluded form the scheduling, although the ground beneath it is included.
