Chelsea pensioners, it seems, aren't the only ones to mature with age.

They've been enjoying a bit of a cheese fest as part of a Christmas tradition dating back 300 years.

It's all part of their annual ceremony of the Christmas cheeses.

Chelsea's Scarlet Army

Cheese has fed the armed forces for centuries.

Back in 1692, a local cheesemonger donated some produce to the Royal Hospital Chelsea as a Christmas treat, and the tradition has continued one way or another ever since.

This is their 57th event and cheesemakers from across the UK have donated their produce for this event.

Mary Johnston got the event off to an official start by cutting the event's ceremonial cheese - a 24-kilogram Montgomery Cheddar:

"It's a great honour to have done it, and I am the first lady to have cut the cheese".

Despite the vast quantities, the cheese does all get eaten, as it's divided out between the pensioners, and Mary, who's still in her first year at the Royal Hospital, is more than happy to keep the tradition going!
