The 'Beefeaters' entertained crowds and gave the public a taste of history at the famous landmark.
It is a role only for ex-service personnel who served in the military for 22 years or more.
Governor of the Tower of London, Brigadier Andrew Jackson, told Forces News: "They really enjoy doing the tours because they're able to inter-relate with a large group of visitors, they're able to entertain them, they're able to bring the Tower of London to life and really stir people's spirits."
The COVID-19 pandemic has hit the Tower of London hard, as with other Historic Royal Palaces – lockdown has cost £100m across six UK sites.
Meanwhile, 54,742 personnel are yet to receive a COVID-19 vaccination.
