Welcome to AiX Glyn.

The nearest Chain Home site to Castlerock is recorded as 'Pottagh' and was spread over this area directly northeast of the village of Articlave:


NGR NV972945

There are some remains according to the Northern Ireland Environmental Agency website

Hi Glyn,
There are quite a few Chain Home locations around that area.
The R.A.F. Castlerock location has 4 or 5 structures remaining.

Your welcome. Various Internet tools are invaluable.

What other interesting places were you at Glyn? Sounds like you might have a story or two to tell....

A selection of photographs of the R.A.F. Castlerock site can be found as follows. Google "Irishmanlost" which is the name of a person on Flickr involved in urban exploration. The "Radar Site" in his sets is R.A.F. Castlerock.

These pictures are of 3 separate builtings at R.A.F. Castlerock which I visited last week.

The smallest building is close to Green Road and the other 2 across the field up a lane behind a house at Ballywoolen Road. I believe there may be another related building beside the house.
The concrete used to hold cables or masts also remains in the fields.

The largest building still has an intact fuel tank inside .....but what were all these used for?

Hope you like the pictures.

Thanks for the pics. What were they used for? Well there was a Transmitter Block and a Receiver Block and although electrical power was probably from the national grid there was usually a Stand-by Generator Building. All of these were protected by earth mounding.

I suggest that you have photographed the interior of all of these. The fuel tank would have supplied the Stand-by Genny

Due to RF valve technology of the time a great deal of heat was produced from the Transmitter and Reciever and was either ducted away or provides with a forced supply of outside air for cooling. One of you pics shows the trunking for either the Tx or Rx.

I feel sure that our RF members can be precise.

Second picture looks like the extractor hood over the radar transmitter in the Tx building.

Have a look a look at this link and search under 'radar'. Lots of pictures and text about all the buildings on loads of sites. You could also google 'radar pages uk' if you are technically minded. The 'West Coast' CH was built to a standard plan so you should get an excellent idea of what it all does.

Sub Brit is good for 'Rotor' but thin on Chain Home. Have a look at this link which gives details and pictures of Hayscastle Cross in Wales. This is a similar site to yours. The fundamental difference being in aerial arrays and reserve equipment. 'Classic' east coast Chain Home had 3 or 4 giant 380' steel towers for the transmitters and 4 240' wooden receiver towers with reserve buried transmitters / receivers and masts close by. West coast sites used 2 guyed transmitter masts, 4 wooden receiver towers and no reserve. They relied on site dispersal for protection.
