The plaque was inaugurated as part of the official ceremonies of 4th November 1925. It commemorates the employees of the Royal Hospitals of Lucca such as the Civil Hospital and Military Hospital of S. Nicolao. These hospitals treated many of the soldiers that were passing or returning from the front. Those who died during their stay - including those not from Lucca - were temporarily buried at the Lucca Urban Cemetery, while awaiting transfer to their different places of origin.
