Portballintrae Indicator Loop.

Portballintrae Indicator Loop.

-

There was an anti-submarine indicator loop station at Portballintrae. I presume they ran across to the other side of the entrance to Loch Foyle to protect the entrance to Londonderry - there is a reference in Admiralty War Diaries to M.3. loop at Londonderry, suggesting that more than one.

-

There are two benches on a concrete base which is said to be where there was an indicator loop building.

-

A short distance North West of there an area of the slope down to beach has been covered in concrete and it is suggested that the cables ran down there.

IC 93185 42358

-

There were some lengths of cable on the beach but I did not see them. I was told in the nearby shop that they are no longer there.

-

There is an area of ground on the hillside above that shows signs of being disturbed either because of some structures or could just have been natural ground movement.
