Ground Survey (9 November 2010)

ND 30996 94650 (centred on) A walkover survey was

undertaken on 9 November 2009 to identify surviving extant

wartime buildings that were part of the Lyness Naval Base.

These would form points of interest along the route of a

circular, self guided leaflet trail. The survey identified 10

previously unknown sites.

of two double door entrances and dog legging passageways

concrete sections bolted together along the central apex of

the roof and built into the northern earth bund surrounding

the WW2 Fleet Repair Base.

ND 3097 9464 [ND39SW 131] A small Anderson type air raid shelter of the

same construction as those mentioned above. It is located

between the rear wall of the pumping station (ND39SW

20.01) and the N–S aligned earth bund to the W of the pump

WW1, deepened and issued with a new cradle in 1941 as

part of the Boat Repair Works.

of the Fleet Repair Base and constructed in the same way as

the repair workshop.

ND 3039 9468 [ND39SW 135] A naval signals station built of rectangular

concrete, brick and corrugated asbestos and surrounded

by a concrete blast wall. It served as the telephone and

teleprinter exchange for Lyness Naval Base August 1939–

September 1944.

ND 2045 9459 [ND39SW 136] A military observation site built of brick

and rendered in concrete this rectangular building is

identifiable by a small second storey tower observation post

with thin horizontal slit windows. It is attached to a timber

prefabricated hut which is in an advanced state of decay.

The observation building served as the main control centre

for the Lyness Naval Base Air Raid Precaution System.
