Maryport Motte (Castle Hill)
My thanks go out to Jan Fialkowski, Facebook friend and photographer-extraordinaire, for providing this photo of the motte, Castle Hill, situated in a loop of the River Ellen in the sea-ward West of the town.
Maryport is a town of Roman remains: the fort of Alauna lies to the North of the town with Roman roads entering from the East and West, pele towers: Nether Hall, a large mansion with a pele tower built largely of dressed Roman stone, no doubt quarried from the nearby fort, Ewanrigg Hall, the site of a 13th century hall with an early pele tower (no longer extant) and Netherhall Park, possibly the site of a medieval moated manor.
Little research seems to have been done regarding whom was responsible for the motte's construction. There are sites on the web that theorise that it could have been built by William FitzDuncan or even Henry II, though, as there are no masonry remains, I would suggest that the motte was an earlier construction, purely of timber and earth and therefore unlikely to be linked with William or Henry.
The site can be access easily, using a number of footpaths that criss-cross this area of the town.
