OK, just a quick report as this has been covered before, but not for a few years.
Visited a few weeks back along with Markymark and D@ywalker.

History:

UNDERGROUND HEADQUARTERS & COMMUNICATIONS CENTRE
With the strategic importance of the Dockyard an underground headquarters and communications centre was planned in 1940.
Two tunnels were driven deep into the hillside to the rear of the dockyard leading to a series of underground rooms based around a central ring.

There were two pairs of entrance tunnels, each pair joining to form single tunnels after twenty yards.
At this junction toilets, washrooms and a small guardroom (in the western tunnel) were located with the twin tunnels extending into the hillside for a further 150 feet to two airlocks.
The control centre is rectangular in shape with a short branch on the south side housing ventilation and heating plant and a standby generator.
After construction, plans were drawn up to extend the control centre with the addition of further tunnels on the north side but this plan was quickly abandoned.

Some from the land-connected end of the breakwater, they're mainly external because it was such a lovely clear night.
