Armed Forces Day occurs on 29 June and local authorities around the country were invited to hoist the flag simultaneously on Monday, 24 June.
Each year, over 3,000 flags are lofted around the British Isles, 500 by local authorities, as the nation demonstrates its support for armed forces personnel.
The flag was hoisted by Tim Cox, Lord-Lieutenant of Warwickshire, as well as Chairman of Warwickshire County Council, Cllr Dave Shilton, Cllr June Tandy and Cllr Bob Stephens and the High Sheriff, Keith Sach.
Mr Cox said: “Armed Forces Day raises the awareness of the commitment of the armed forces and of our gratitude towards service personnel for the sacrifices they make on a daily basis.”
Chairman of Warwickshire County Council, Cllr Dave Shilton, said: “The County Council is pleased to show its commitment to armed forces personnel, past and present.”
Cllr June Tandy, Leader of the Labour Group also lent her support and said: “We owe a debt of gratitude to the members of the armed forces so raising the flag, and showing our support, is something that we are proud to do.”
