Wall Mile 74 [HB 358]
As with Wall Mile 73, nothing is known about Wall Mile 74. We may note the settlement of Boustead Hill, off to our left beyond the abandoned railway line. This is perched on a drumlinoid, a glacial feature in the form of a low mound amidst the mosses and marshes along this stretch of the estuarine coast. As we shall see, the Romans made good use of drumlinoids further on. In the absence of anything else of interest, now might be a good time to consider that railway line and its unusual predecessor.
To our left, behind the levee (designed to stop the farmland behind flooding with seawater) lies the route of the former Carlisle Canal, which was opened in 1823 and then closed only 30 years later. Designed to give Carlisle a link to the sea and, therefore, coastal trade, it was soon rendered superfluous by the arrival of the railways. Indeed, the canal was filled in and the Port Carlisle Railway replaced it in 1854. This stretch was shut in 1964, whilst that from Drumburgh to Port Carlisle closed even earlier, in 1932. From the air, the canal-cum-railway is the most prominent linear feature around here now (and is in fact occasionally mistaken for the Vallum).
