King Frederik I of Sweden was given gifts from the Bey of Algiers in 1731. These included a lion, another wildcat, three hyenas, and a freed slave who became the animals’ keeper. The creatures lived out their lives at Djurgården, the Royal Game Park. Quite a few years after the lion died, some of its remains were sent to a taxidermist to be mounted. All that was left was the pelt and some bones. The taxidermist was not at all familiar with this animal called a lion. So he did the best he could with what he had.

The website for Gripsholm Castle doesn’t mention the lion but does look like it would be a wonderful place to visit.
