The “Burrell MSS.” state that:—“There are three Roman castra, or camps, lying in a line over-thwart the Downs from Brighthelmstone to Ditchelling, from south to north. The first, a large one, called the Castle, about a mile from Brighton, eastward, and a mile from the sea, on the summit of a lofty hill commanding the sea-coast; the next, a smaller, called Hollingbury Castle, nearly about the middle of the Downs, also commanding from a lofty hill, by Stanmer, the whole western sea-coast of Sussex; and a third, a large one, called Ditchelling Castle, containing between twelve and fourteen acres, is the highest point of the Downs thereabouts, and commands part of the sea-coast, and all the northern edge of the Downs, and the wild underneath it.” A military Roman way was discovered a few years ago, on St. John’s Common, and in the enclosed lands adjoining, in the parishes of Keymer and Clayton, fully confirming the opinion of Camden and Stillingfleet that the _Portus Adurni_ of the Romans was at Aldrington. {2} On the west side also of Glynd Bridge, near Lewes, a paved Roman causeway was discovered, lying three feet beneath the turf, upon a bed of silt, or blue clay, twenty feet thick; and near it was found a large brass coin of Antoninus Pius. By whatever name Brighton was then known, there is no doubt it was a place of some note in the time of the Romans, as it was peculiarly favourable to all the purposes of the fisher and the hunter. Romish coins are still frequently found in its vicinity, and in the year 1750, near the town, an urn was dug up, which contained a thousand _denarii_ of different impresses from Antoninus Pius to the Emperor Philip; and since that time there have been found in some of the burghs or barrows to the east of the town, ashes and fragments of human bones, enclosed in urns of Roman manufacture. In preparing the ground for enclosing of the Old Stein, in 1818, several Roman coins were turned up by the workmen, on one of which, round the impression of the head, was the inscription, “IMP. ALEXANDER PIUS, A. V. C,” and on the reverse, “MARS ULTOR,” with the initials S. C. between the figure of Mars. The date, however, was illegible. In forming the Race Course to the south of the Stand,—since restored to its original state,—several urns of Roman fabrication were dug up; and since then, to the east of the town, ashes and fragments of human bones have been found enclosed in Roman urns.
