As its 20th anniversary approaches, the museum is currently closed for a major revamp. The new exhibition will employ the latest display methods to narrate the history of Hong Kong's coastal defences and military affairs. Several new topics will be featured, including the Tang dynasty garrison camp in Tuen Mun, the famous warships that berthed in Hong Kong over the years, as well as the stories of the British-Chinese and Gurkha soldiers who served here.
