A programme of building recording (English Heritage Level 3) was carried out by the Colchester Archaeological Trust on surviving structures at the decommissioned Hyderabad and Meeanee Barracks on Colchester Garrison, in advance of residential conversion. These include the original Guard House, Brigade Offices and Officers’ Mess and Quarters of Meeanee Barracks, and the Officers’ Mess and Quarters and the Regimental Institute of Hyderabad Barracks. All are brick buildings dating from the late 19th century/early 20th century, with later additions and alterations. The significance of the buildings lies in their association with past military events and the sea change in military thinking after the Crimean War that is reflected in the layout and design of the buildings.
