Orpington Hospital, first built to care those soldiers wounded in the First World War, is hosting a special memorial service as the centenary is commemorated.
Today (August 4) marks 100 years since the outbreak of the conflict - and the Ontario Military Hospital was built soon after where the current NHS facility now stands.
Although much has changed, the history remains, and on Friday August 8 staff are gathering in the newly developed memorial garden to remember those who fought and were treated at Orpington.
The garden houses the original clock tower from the original site, which has been restored and now stands as a poignant reminder of over 30,000 soldiers who passed through the hospital's doors.
The event will see the deputy high commissioner from the Canadian High Commission, who will unveil a new plaque and plant a maple tree, as well as a blessing from the Bishop of Rochester.
