I was just taking a different route into Dartmouth and stumbled across this and thought it was quite picturesque.
There really is very little information I could find on the creek, so if any one knows anything please post in the comments below.
Old Mill Creek marks the parish boundary between Dartmouth and Dittisham. The picturesque bridge crossing it is thought to date from the eighteenth or early nineteenth century, as does the limekiln beside it, once used to burn limestone to make fertiliser. Further down the creek, on the Dartmouth side, is a circular tower known as Hermitage Castle. From stonework bearing a fragment of a date this folly is thought to date from either 1790 or 1890, although the lower levels may have been from an earlier building on the site.
There are abandoned hulks, timber skeletons of a ketch, a trawler and a barg all lie in the mud in the creek.
