Grongar Hill is located in the Welsh county of Carmarthenshire and was the subject of a loco-descriptive poem by John Dyer. Published in two versions in 1726, during the Augustan period, its celebration of the individual experience of the landscape makes it a precursor of Romanticism. As a prospect poem, it has been the subject of continuing debate over how far it meets artistic canons.
