The 14th-century chivalric romantic poem Sir Gawain and the Green Knight depicts its conclusion as taking place in the district. This is partly due to the fact that the dialect in which the poem is written is now accepted by scholars as closely resembling that of the district, and also partly due to the extensive local work of R.W.V. Elliot in the 1970s. This has led some to try to identify precisely the actual location of the story's climax. Mabel Day (1940) proposed Nan Tor Cave, at the bottom of the valley where the Hoo Brook runs into the Manifold at Wetton Mill (near the site of the Wetton Mill train station), as a candidate for the Green Chapel. Her idea was later examined in detail by Robert Kaske (1972).
