Former radar station. [1]
Should not be confused with the better known aerials at NHER 14227. Part derelict, part built over for housing. A number of defensive positions remain around the perimeter.

In 1997 a large stone was dug up within the radar station area but this proved to be a glacial erratic. Photograph in secondary file in order to avoid misunderstandings at a later date.

The site of a World War Two radar station is visible on aerial photographs alongside Chandler Road at Upper Stoke (S5-S6). The site is centred on TG 2526 0270. Stoke Holy Cross radar station forms part of the main chain for the national Chain Home radar network, and its construction relates to a planned expansion of the original Chain network in late 1937 to early 1938 (S7), and was in operation by 1939, with three timber towers completed by January 1937 (S8). The radar station is split across two sites, almost 400m apart. The larger site to the east (NHER 14227) acted as the transmitter site with four steel transmitter towers. This site forms the receiver site with four timber receiver masts arranged to a trapezoidal plan, all approximately 75m apart.
The rectangular receiver block is located within the centre of the four towers and is surrounded by a broad earthen bank. The ‘Buried Reserve’, an underground receiver block, is located approximately 180m to the east in the adjoining field (NHER 32835). The remainder of the site consists of a variety of huts and operational buildings. One of these structures will have been the Stand-by-Set House, which maintained the power supply.
The perimeter of the site is defended by four AM5 pillboxes, at TG 2519 0267, TG 2529 0276, TG 2532 0270 and TG 2529 0260. At least two of these, the southern and western facing examples, have mounted gun positions on top (Light Anti-Aircraft 20mm chimney mounts according to above entry). Although it is really hard to discern for certain, the perimeter of the site appears to be surrounded by a barbed wire obstruction.
Outside of the main site there is the rectangular entrance to an underground air raid shelter at TG 2534 0273 and a spigot mortar emplacement at TG 2533 0277. On the roads opposite to the site a series of fairly regularly spaced disturbed areas are visible, it is possible that there represent the remains of weapons pits or similar defensive positions.
