Nova Scotia-based Heritage Memorials constructed a tomb of an unknown soldier for the Newfoundland National War Memorial in St. John's. The 3,600-kilogram sarcophagus portion of the tomb was installed at the base of the war memorial on April 9, 2024. The remains of an unknown Newfoundland soldier who died in the First World War were repatriated from a battlefield in northern France and placed inside the tomb.

The vault, carved from black granite that was mined from a Quebec quarry, is inscribed with the words "Known Unto God" in English and French. A forget-me-not flower — a symbol of remembrance for the Newfoundland Regiment — is also carved into the granite. The province's coat-of-arms is carved into the front of the tomb.

The cover is carved from Labrador granite called "Blue Eyes" and weighs roughly 1,100 kilograms.
