Rocque du Guet Watch-house and Battery, Guernsey

Information taken from the information board fixed to the outer wall.

The watch-house and battery were built as part of the chain of observation posts and signalling points erected against the threat of French invasion before and during the Napoleonic wars.
Other sites were at the Catioroc and Noirmont, also on the west coast.
It is certain that some form of watch was kept here from as early as the sixteenth century as the site is mentioned in a document of 1581

From 1756 a corporal and four privates of the militia manned the post from 5pm until 7am. The watch-house served as an important post during the First World War. During the Second World War the German occupying forces added extensive new fortifications.

The watch-house and the land surrounding it were purchased by the States of Guernsey in 1938 from its owner Lord de Saumarez.
