In May, Buckingham Palace announced the prince would retire from royal duties in the fall, while the 91-year-old queen would continue with her full program of official engagements.
The Duke of Edinburgh, Captain General of the Royal Marines, was marking his final solo appearance by attending a tribute to royal marines.
Prince Philip was hospitalized earlier this summer for two nights as he received treatment for an infection caused by an undisclosed preexisting condition.
