Dover has ever, from Roman times, been a place of arms, and was, an old chronicler tells us the “lock and key of the whole kingdom.” That being so, it has always behoved us to make it one of the most strongly fortified places on our coasts. On either side of the deep and narrow valley in which the town lies, the great chalk downs and cliffs rise steeply and massively, and all are in military occupation. The morning drum-beat reverberates from the Western Heights to welcome the rising sun, and the Last Post from the Castle sounds the requiem of the departed day; and in between them the tootling and the fifing, the words of command, the gun-firing, and all the military alarms and excursions of a garrison-town help to convince even the most timid that we are being taken care of.
Dover Castle, that “great fortress, reverend and worshipful,” sits regally on the lofty cliffs ….. It occupies a site of thirty-five acres within its ceinture of curtain-walls, studded at intervals with twenty-six defensible towers, of every size and shape. The chief entrance to the Castle precincts is by the great “Constable’s Tower,” also variously styled Fiennes, or Newgate Tower, to distinguish it from the Old Tower, formerly the principal entrance. Besides this imposing array there were, and there remain still, profoundly deep ditches outside the walls. In midst of all these outworks, rising bold and massive as the great keep of the Tower of London itself, is the Palace Tower, or Keep.
The most ancient and venerable object here – supposed to have been built A.D. 49 – is the Roman pharos, or light-house, one of two that once guided the ships of the Roman emperors into the haven that was situated where the Market-place of Dover now stands. The other, of which only the platform and one fragment of stone have been found was situated on the western heights.
Many generations have tinkered and repaired the Roman pharos, whose original tufa blocks and courses of red tiles still defy the elements and the ravages of mischievous hands, while the casing of flint and pebbles set in concrete, added some two centuries ago, long since began to decay. The Roman windows were altered by Gundulf [William the Conqueror’s architect], and the upper story would seem to be the work of Sir Thomas Erpingham, the Constable of Dover Castle in the reign of Henry the Fifth, for his sculptured shield of arms appears on it.
