The Vampire dugout (known locally in Belgium as the Vampyr dugout), is a First World War underground shelter located near the Belgian village of Zonnebeke. It was created as a British brigade headquarters in early 1918 by the 171st Tunnelling Company of the Royal Engineers after the Third Battle of Ypres/Battle of Passchendaele. Rediscovered in 2007, the Vampire dugout was the subject of a 2008 British television programme (Time Team) which was also broadcast abroad. The structure is inaccessible to the public, but inspected regularly by battlefield historians.
