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.

October 2009

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.

"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"

the gatehouse, the last crumbling remnant, is said  to have fallen down in May, 1815.

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.

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.
