Hobajon's Cross
Granite cross between Harford and Ugborough, probably a reused prehistoric stone-row stone. It became a parish boundary marker in 1782-84.
Dartmoor has more stone crosses than most people expect. Harrison counted 132 within the National Park boundary, and Wikipedia's article on the subject repeats that figure. They were put up over a long stretch of time, the earliest probably almost 1,000 years ago and some as recently as 100 years ago. The moor has no tidy count: the Dartmoor Crosses site started out in 2000 aiming to document 150, posted its 200th page in May 2021, and says new discoveries are still occasionally made.
They were not all put up for the same reason. William Crossing, in his 1902 book, wrote that on the open moor crosses were set up either to mark a boundary or as guides to the wayfarer, while market crosses and churchyard crosses belong to the villages around it. Often it is both, and sometimes nobody can say which came first. Crossing could not decide whether Bennett's Cross was meant to mark a boundary or the path, and thought it probably did both.
