Radio Room
This was a very important project, as the room was lined with asbestos and occupied by the
Post Office who used it in the late 1950's & 1960's. To make the room safe,a specialist
asbestos removal company were employed. As they worked, they had to remove the floor and
the only timber wall. These were replaced with new materials by the Society members,and
painted in the original colour scheme. The room now houses a display of period radio and
associated equipment.

Drainage System
The site receives a lot of rain, and is tunneled through a porous rock type. This requires a
drainage system, which runs below the tunnel floors, with sumps spaced at regular intervals.
Over the years these sumps had become filled with soil, rocks and other detritus. All of the
sumps have been cleared and covered. The gutters have also been fitted with new grilles. An
ongoing project is seeing that the covers are kept in good repair, and replaced when no
longer serviceable.

Bearing Marks In Number One Gun Pit
Each gun pit was marked with a protractor around its rim. This was aligned so that 0 degrees
pointed North, as with a compass, but was used to point the gun in the required direction.
This gave the horizontal bearing when laying the gun. These marks have been repainted by the
diligent efforts of a member, over several months, and now form an important visual feature
of the Gun Pit.
