The Blorenege Zero station is located right at the top of the Blorenge, a flat topped mountain just outside
Abergavenny. The suitability of the site for long range communication is shown by the modern transmitter mast a
couple of hundred meters away. The remains of the OB can be easily found by walking past the “Foxhunter” memorial
and towards a nearby bench. This overlooks the remains of the OB. There is a convenient parking area next to the
memorial. NGR SO264108
The OB has the classic Zero station layout of three Chambers. It is built from hollow blocks, similar to those
used at Rudry. The entrance was down a rectangular shaft which would have been camouflaged during the war.

The OB is now half full of rubble, apparently deliberately put into the OB to render is less accessible and
dangerous. The corrugated iron roof has collapsed in a couple of places which allows access to the larger
The view into the entrance chamber.
Notice how there is an outline of unpainted blockwork around the doorway through to the second chamber. It is
known that there was often a disguise over the first doorway, such as a set of shelves, which would have been
released by a hidden catch. The aim was to confuse those fiding the OB long enough to allow the escape tunnel
to be used.

Notice the impression in the paint above the wooden lintel. This may have been where a blackout curtain was
fixed to the wall with a wooden batten.
The entrance to the escape tunnel in the end wall of the OB.
The escape tunnel is short and built of blocks with a flat roof of concrete slabs. It lies barely
below ground level. The tunnel leads into a long destroyed prefabricated concrete hut.
The remains the the prefabricated hut.
A few bricks, a front step and sections of the supports for the wall panels are all almost that remains. In a
couple of places the very bottom of prefabricated concrete wall panels remain in situ, there upper portions
broken off when the hut was destroyed.
The is no definitive evidence, but it is quite likely that this was also part of the wartime Zero Station –
being the above ground “Met Hut” used day to day for Signals duties. The OB would only be used for specific
exercises or in the event of invasion. It is not known how the aerials were sited in this treeless location.
Another Welsh Zero station on moorland used a specially constructed fire watchers tower, with the aerial built
into the uppermost handrail. It would be interesting to see a wartime aerial photo of the site.
Linked sites (including local HQs and accommodation): It is likely that ATS operators were
billeted in a nearby village, though it is uncertain which one. It would have been a tough cycle ride to the
Zero station and it is a steep climb even in a modern car!
The Harcourt wireless network would have included a number of other locations, though full details are not
available. These probably included the outstation at Rudry
as well as
the one at Llantillo Church, mentioned by George Vater in the Mercian Maquis. There are reports that there was
another outstation in a locker at Newport Golf Club.
