Prince Charles no longer owns the Blimp's Mead Estate, a six-bedroom mansion near Dartmoor National Park in Devon. According to the [Times] (open in new tab), the prince sold the mansion, which is currently listed for sale for $6.7 million, to a couple in 1993 for an undisclosed sum. The mansion was built between 1893 and 1906 and includes two cottages, a riverfront, and a paddock. Sounds lovely!

But now that Blimp's Mead is for sale again, prospective buyers may want to know about the special rules the prince made the first buyers agree to, and which apply to the new owners. The estate is theirs, but Prince Charles reserves the right to come fishing whenever he wants, with 24 hours' notice.

If this sounds like a strange contract clause, that's because it certainly is. But from a royal perspective, it makes sense: according to People magazine, the mansion itself can be sold, but the land surrounding it belongs to the Duchy of Cornwall, which Edward III started in 1337 to provide income for his heirs.

The Duchy of Cornwall still holds title to 130,000 acres in 23 counties, including 160 miles of the English coast. In addition, Prince William will succeed to the Duchy when Prince Charles ascends to the throne.

According to the Times, Prince Charles has never actually had the opportunity to drop in on the owner of Brims Mead without a day's notice, but the avid fisherman may one day. Whether the purchase of the mansion will have a positive or negative effect will probably depend on his attitude toward the monarchy in 2021.
