| Great Grimpen Mire |
|Location||Dartmoor, Devon, England|
|Appearances||The Hound of the Baskervilles|
The Great Grimpen Mire was a vast bog, deep in the heart of Dartmoor in Devon. It was connected in local lore to the legend of the fell Hound which beset the Baskerville family in "The Hound of the Baskervilles".
There were but a few settlements located within the mire. At its center was the hamlet of Grimpen, seat of the parish of the same name, where Dr James Mortimer had his practice. There were also several scattered and isolated farms and houses, including Baskerville Hall, Sir Charles Baskerville's ancestral house; Merripit House, residence of Jack and Beryl Stapleton; Lafter Hall, home to Mr Frankland; and the farms of High Tor and Foulmire. The nearest town was Coombe Tracey. Dartmoor Prison was located on the edge of the mire, fourteen miles from Grimpen.
