Now known as Reculver, is situated about three miles to the east of Herne Bay. The site, although originally some distance inland, is now, owing to the encroachment of the sea, quite close to the shore. Indeed, about half of its area has been destroyed by the waves, and is now covered at high water. Its area when complete was over seven acres, and its walls which, in the eighteenth century, stood 10 feet high, and still remain to a height of 8 feet in some places, are no less than 8 feet in thickness with two sets-off inside. It seems doubtful whether there was ever a ditch round the castrum. Owing to the ruinous condition of the main part of the masonry, and the complete destruction which has overtaken the northern part of the foundations, it is impossible to ascertain any particulars as to the gates or internal arrangements.

As will be seen from the accompanying ground-plan the form of the castrum at Reculver was quadrangular. The angles were rounded, but there are no indications of towers or bastions. These features are considered characteristic of Roman fortresses of early date. Another feature pointing to the same conclusion is the absence of tile courses in the walls.
The only recorded facts about this fortress is a mention in the “Notitia,” from which we learn that it was garrisoned by the first cohort of the Vetasians commanded by a tribune.
FIG. 6. RECULVER: THE RUINS OF THE CHURCH
At a comparatively early stage in the art of Roman masonry in Britain the idea was conceived of protecting the enclosing wall of the fortress by means of projecting bastions and towers. In an early type represented in the Romano-British coast fortresses, of which this of Reculver is an excellent illustration, there were, as we have seen, no projections whether of walls, bastions, towers, or gates. Reliance was placed in the strength and solidity of the walls themselves, which were 8 feet in thickness. But the desirability of having some points from which the enemy could be attacked in flank whilst battering the wall soon became evident, and in other cases such as Richborough, Lymne, Pevensey, etc., we find that the fortress was furnished not only with massive walls, but also with strong angle-towers and bastions or towers at intervals by which the wall could be commanded and protected.
These various works furnish an interesting series of illustrations of the progress made in the military architecture of the period.
