Back Lane drill hall

The building was designed as the headquarters of the 5th Volunteer Battalion, The South Wales Borderers and was completed in 1897. This unit evolved to become the 7th Battalion, The Royal Welch Fusiliers in 1908. The battalion was mobilised at the drill hall in August 1914 before being deployed to Gallipoli and ultimately to the Western Front. After the Second World War, the battalion converted to become the 636th Light Anti-Aircraft Regiment, Royal Artillery (Royal Welch) and then amalgamated with the 635th (Royal Welch) Light Anti-Aircraft Regiment Royal Artillery to form the 446th (Royal Welch) Airborne Light Anti-Aircraft Regiment Royal Artillery at Caernarfon Barracks in 1955.
