Until recently there was an octagonal blockwork structure in Addlethorpe which was almost certainly the remains of a direction-finding (D/F) homer.

This World War 2 device housed a radio transmitter to help bombers track their return journeys from the continent to RAF bases in the UK.

The solid blockwork base (about 5m across and 2m high) supported a tall octagonal wooden tower.

SLHA would welcome more information about this particular structure.

Over 170,000 men of the Machine Gun Corps trained in the grounds of Belton House during the First World War, an area which had been used by local volunteer forces since the 1880s.

Accommodation for the troops was initially in bell tents but they were replaced in 1915 by prefabricated wooden huts (shown here).

Supplies to the camp were carried on a standard gauge branch line from the main line at Peascliffe north of Grantham.

The Belfast Truss roof was a novel form of construction that used laminated wooden lattice-braced roof trusses to provide a large clear span which was (27 m here) to accommodate aircraft.

This site was originally the aerodrome of Robey & Co Ltd but it became No 4 Aircraft Acceptance Park.

In WWII AV Roe repaired damaged Lancaster bombers here and latterly it was used as a road haulage depot.

The hangars, which dated to 1916, were demolished in 2001.

The guardhouse at the entrance to the Mere Y Station site was built in the 1950s at the time of the Cold War.

The site ceased to operate in about 1954.

One of the very first stations for listening to wireless traffic was set up in 1927 at the hamlet of Mere, about two miles south of Branston village centre.

The station continued in operation – playing an important and secretive role – until the 1950s.

The base of one of the 4 or 5 receiver masts from the 1930s can be seen in the small area of woodland alongside the site.

The operations room or signal receiver building was built in the 1950s and is now used as an agricultural building.

It replaced WW2 wooden huts where Morse signals were received, often giving early warnings of Luftwaffe activity.

Transmissions were taken daily by RAF despatch rider to Cheadle and later to Bletchley for decoding.

Reopened in 1959 as an RAF Bomber Command Intermediate Range Ballistic Missile (IRBM) launch facility and placed on a high DEFCON 2 launch alert during the Cuban Missile Crisis, the station was finally closed and decommissioned in 1963.

RAF and NATO aircraft use the range for dropping bombs and firing cannon.

Targets include old trawlers beached on the mudflats of the Wash.

During the Cold War period a network of Royal Observer Corps bunkers was created covering the country.

Most, like this one near Holbeach, were in isolated locations with telephone links to regional bases. (The HQ for Lincolnshire was at Fiskerton).

They were manned at all times by ROC volunteers and were equipped to detect attacks by nuclear weapons.

"Built in 1901 to replace an earlier Drill Hall with money raised from public donations.

It was used for army training and also as a venue for entertainments for the town.

During WW1 and WW2 it was used as a hospital and treatment centre.

In 1967 it was renamed at The Town Hall.

In 1974 East Liindsey District Council created their local office there along with the Town Council Offices.

In 2009 the hall was boarded up ready for demolition as ELDC decided it was surplus to requirements.

The town's people rallied round and the lease was finally signed on July 30th 2010 and the utilities and services were re-commissioned along with the removal of the boards.

It was re-named The Stanhope Hall after Edward Stanhope who was MP in 1901.

"The castle was the focus of attention during the First Battle of Lincoln on 2 February 1141, during the struggle between King Stephen and Empress Matilda over who should be monarch in England. It was held but damaged, and a new tower, called the Lucy Tower, was built.

Lincoln Castle was again besieged before the Second Battle of Lincoln, on 20 May 1217, during the reign of Henry III of England during the course of the First Barons' War. This was the period of political struggle that followed the sealing of Magna Carta on 15 June 1215"

This 360ft (110m) high steel lattice tower at Stenigot (TF 257825) is the only survivor of four transmitting towers forming part of RAF Stenigot Chain Home Radar Station.

The Chain Home system, developed during the Second World War, was the world's first air defence radar system.

Although the site is known as RAF Stenigot it is actually in the parish of Donington.


Chris Lester, 1997

A view of RAF Stenigot from the top of the surviving transmitter tower, looking north, taken in 1995.

The building in the left foreground housed a 1950s GEE-H Master Station used for aircraft navigation.

To its right can be seen the bases of another of the four Chain Home transmitter masts.

The building in the right foreground is the Slave Receiver hut of the original wartime GEE installation. Beyond that is the water tower and beyond that is the Standby Set House which housed a diesel generator to provide emergency power.

The 1960s NATO ACE HIGH tropospheric scatter station is located in the fenced compound beyond it.

It is obstructing sight of the Chain Home Receiver building although the four concrete bases of one of the receiver masts can be seen beyond the fence and to the right of the dishes.

Approximately 120 RAF personnel manned the Chain Home site, including police and anti-aircraft gunners to protect it.

This building housed the radar receivers, a calculator room which converted the raw radar data into grid references and altitudes, and a plotting area which was manned largely by WAAFs.

It was situated between four 73 m (240 ft) high wooden receiver masts arranged in a rhomboid pattern.

This Grade II listed building was recently demolished.
