The fruitcake is one of about 1,500 artifacts discovered in a building in Cape Adare, an Antarctic peninsula.
A team has been working on conserving artefacts from Cape Adare since 2016.
You might not want to take a bite out of it, but the Antarctic Heritage Trust claim the fruitcake made by Huntley and Palmers is in "excellent condition" and still wrapped in paper.
The fruitcake itself dates back to the Terra Nova expedition (1910-1913) headed by Robert Falcon Scott.
Programme Manager-Artefacts Lizzie Meek said finding such a "perfectly preserved fruitcake" in a severely corroded tin was a huge surprise.
"It's an ideal high-energy food for Antarctic conditions, and is still a favourite item on modern trips to the ice".
It has been documented that he took this specific brand of fruitcake with him. His team of five eventually reached the geographic South Pole on January 17, 1912, only to find that a Norwegian team led by Roald Amundsen beat them by 34 days.
Tragically, the cake may have survived, but Scott's entire party died on the return journey from the pole.
They were built and used by Norwegian Carsten Borchgrevink's expedition in 1899 and used again by Captain Scott's party in 1911. The artefacts be returned to the huts once they are restored to comply with the site's status as an Antarctic Specially Protected Area (ASPA). "The tin has suffered significantly in the harsh Antarctic elements, however the Trust says the cake within looks and smells "(almost) edible". Conservationists recently discovered a 106-year-old fruitcake and its perfectly fresh and edible!
So it doesn't appear that anyone will be eating this fruitcake anytime soon, which is just as well.
