We have now glanced at those churches which contain remnants of Roman ruins, and others which are built over Roman villas, or within Roman camps, and we have been led insensibly to examine buildings which are connected with earthworks of other ages. The problem of site-continuity has constantly impinged upon the question of continuity of fabrics. A few paragraphs may now be devoted to a consideration of those churches which lay claim to a possession of one or both of these features. The small ruined church of St Mary, within the confines of Dover Castle, is a well-known example. It stands in juxtaposition with an octagonal structure, usually described as a pharos, or lighthouse (Fig. 5), and believed by some to be a fort belonging to the Romano-British period. This polygonal tower has an exterior casing of flint, dating from the fifteenth century, but the original uneven masonry of rubble and flint, bonded with bricks at intervals, is still visible at the base. The supposition is that the church, with the lighthouse, was utilized for Christian worship during Roman times. By most modern authorities, the church itself is attributed, and perhaps more correctly, to the late Saxon period[64]. Lyminge, in Kent (p. 4 _supra_), is another claimant. The foundations of a seventh-century chapel, probably of apsidal basilican plan (Fig. 6), have been traced here (A.D. 1899), but it is supposed that the present church, though rich in Roman materials, belongs entirely to a later epoch[65]. At Reculver (Regulbium), near Herne Bay, there is an example of a church which Professor Baldwin Brown places with that of Dover in a distinct category as representing possible authentic relics, since the buildings stand alone within deserted Roman stations. The church at Reculver stands over the foundations of a basilica, but the present building is probably altogether post-Roman, the earliest known date for the existence of a church on this spot being A.D. 670[66]. Dean Stanley held the belief, once shared by many antiquaries, that in St Martin’s at Canterbury we have a veritable monument of early British Christianity--a monument, moreover, erected over a pagan temple[67]. Bede asserts that there [Illustration: FIG. 6. Chancel of Lyminge Church, Kent. In the churchyard, to the right hand, is a portion of the foundations of a seventh-century chapel, composed of re-arranged Roman materials. The church seems to occupy the site of a villa. ] [Illustration: FIG. 7. Portion of chancel wall, south side, St Martin’s Church, Canterbury. Roman tiles are seen abundantly in the wall on the right, and in the round arch; they are also bonded into the wall on the left. The wall is mainly seventh-century work, but the round-headed doorway is later, and the buttress has been modernized. The flat-headed doorway is probably original. ]
