Researchers at the British Library have inadvertently stumbled upon what appears to be an "eccentric" architectural plan drawn by King George III. Drawn during his period of madness, it offers a bizarre glimpse into the long-reigning monarch's deteriorating state of mind.

The plan, which is part of a massive collection of papers put together by George III during his tenure as British king from 1760 to 1820, was found hidden inside a volume at the British Library. The plan was drawn on a loose sheet of paper by hand in ink over a pencil outline. Experts say George III drew it "in a rather savage way," and that there are certain things within the plan that are "odd and actually rather disturbing."

The Telegraph reports:

A grand central courtyard with no obvious means of access, surrounded by no fewer than four monumental staircases, was "perhaps a little excessive, even for a Baroque monarch", Mr [Peter] Barber said.

Meanwhile, some of the rooms have no doors at all, and there is no way of getting from one room to the next.

The experts added that it's "enthusiastic," and "slightly obsessive in places." And it's this obsessiveness, along with George's easily identifiable handwriting style, that's leading the experts to conclude that it's the real deal.

The British Monarch, who was famously portrayed in The Madness of King George, probably suffered from the blood disorder porphyria, or possibly bipolar disorder.
