Carved out of the sandstone cliff overlooking the Hart Burn, a little upstream from the village of the same name, can be found a curious manmade cavern – created, rather daftly, for use as a changing room for those mad enough to want to bathe in the nearby river. It is known as Hartburn Grotto.
Dr John Sharp was vicar of Hartburn for forty-odd years from 1749, and it was he, with the help of his parishioners (who must have laboured with some puzzlement), who built the said structure in around 1760. It has a high, slit-like entrance, with two niches for statues above; and an internal gothic arch, which separates the inner and outer chambers – one of which contains a fireplace. The said niches used to hold statues of Adam and Eve. And, best of all, there is a 15m-long underground tunnel from the grotto down to the river, allowing bathers discrete access to the watery facilities.
Many believe that the monument’s likeness to a rough-cut chapel may hint at an earlier manmade origin for this strange fold in the landscape – almost certainly expanding upon what would have originally been a natural cave or cleft in the cliff face. Its closeness to the Devil’s Causeway could well mean that a Roman temple may have occupied the site – and if not, then there may well be some other distant spiritual connection to an earlier age.
Coincidentally, the grotto lies a few yards away from the site of a former Roman river crossing of the Hart Burn, where the aforementioned Devil’s Causeway spanned the wooded valley. Faint traces of Roman engineering can still be found in the river, rocks and landscape thereabouts.
