Located on the isle of Portland, High Angle Battery is a late Victorian gun battery built to help defend Portland Harbour against invasion.

Constructed in the 1890s, its purpose was to fire shells at a high angle onto attacking ships below. The battery’s high position and network of below-ground buildings, tunnels and concealed gun emplacements made it almost invisible to enemy warships.

But, despite its formidable design, advancements in ship speed meant the site quickly became obsolete. The battery went out of use after only 10 years, never firing a single shot in combat

The High Angle Battery (HAB) – or as it is often locally known, the Ghost Tunnels – are already an integral part of Portland’s landscape.  HAB is a place of memory and reflection, of outdoor leisure, and – particularly for young people – a place of exploration.

Re-discovering High Angle Battery project aims to rejuvenate the site and help tell its story to a wider audience. You can find out more about the project HERE.
