Twentieth Century Military Sites outlines Wales's role during a century dominated by war and conflict - and the effect this had on the landscape.

Thanks to its strategic position on the western seaboard, Wales was on the front line for the Battle of the Atlantic, guarding against a possible German invasion from Ireland.

Wales was also an important location for training, munitions manufacture and weapons testing; it was defended to a level which was almost on a par with south-east England. Examples of World War II relics existing to this day include a pillbox at Nant Ffrancon.

While many of the military sites were cleared after hostilities ceased, the battle scars are still fresh, especially for those who lost relatives or loved ones during the wars of the 20th Century, say the authors.

The key objective of the leaflet is to raise awareness of the rôle and significance of these sites.

Many have been destroyed as part of clearance and improvement programmes, but those surviving help us to understand momentous historical events, say the authors.

The sites also retain an important commemorative function, remembering the fallen and acting as a testament to the human cost of war.

Twentieth Century Military Sites, co-written by Jonathan Berry and Bill Reid, is published by Cadw. For a free copy contact Kaye Moxon on 01443 336072.
