A WWII concrete and steel Spigot mortar base, lying on its side beside the path leading up the shingle ridge that separates the beach from the salt marshes; the path skirts the grassed-over Roman site on Gramborough Hill. See also > 748162. Defence of Britain database ref: S0001110. The village of Salthouse can be seen in the distance beyond the saltmarshes. Gramborough Hill belongs to the National Trust. A Romano-British settlement once occupied this site - a grassed-over hill composed of gravels and sands and a thin layer of top soil - rising from the surrounding marsh to approximately 30 metres in height, offering good views across the surrounding land. It is believed that in Roman times the shoreline reached out into the sea for another mile and that the hill might have been situated on the edge of an estuary, with a fort guarding the entrance. A number of Roman bricks and pottery sherds have been found here over the years, with the most notable find (to-date) being a bronze bird (or duck). The chief feature of the site is a small pit, about 100 cm in diameter and 90 cm deep, sunk in the natural gravel. See > https://www.geograph.org.uk/photo/825819 for a wider view of this site.
