The central tower of the church of St. Nicholas is square and small, and so low as to admit only a single tier of semi-circular-headed windows, four on each side. It terminates in a ridged roof, and apparently, never was higher; though, as far as may be judged from analogy, a greater elevation was probably designed by the architect. Along the sides of the church, immediately beneath the roof, runs a bold projecting cornice, of antique pattern, formed of numerous horizontal mouldings; and, under this, the corbel-table presents only a row of plain knobs, instead of the monsters commonly found in Norman buildings. The clerestory, throughout both the nave and choir, is filled with narrow arches, alternately pierced for windows, and left blank. All these arches, as well as the windows of the transepts and of the projecting aisles below, are without the accompaniment of pillars or ornaments of any description, excepting a broad flat moulding of the simplest kind, which wholly encircles them. The disposition of the windows in the lower part of the nave, differs from that of those above, in their being separated from each other by shallow buttresses, which hold the place of the blank arches. A plain string-course also is continued the whole length of the church beneath the windows, as in the west front. On the south side is a door, the only one now in use in the church, which is entered by a very noble Norman arch, composed of a great number of cylindrical mouldings, arranged in three broad bands, but without pillars or capitals, and with no other variation than that of size, and of the addition of the billet-moulding to the outer row. The transome-stone of this arch is unquestionably coeval with the arch itself, the sculpture of the masonry being interwoven with it. Attached to the eastern side of both the transepts, is a circular chapel, as in the churches of St. Georges, of St. Taurin at Evreux, of Fécamp, of Cerisy, and in several other ancient religious buildings in Normandy. Nor is England altogether without specimens of the same kind: a similar chapel, now in a ruinous state, and called by Blomefield, "the sexterie or ancient vestry," is joined to the north transept of Norwich cathedral; and near the eastern extremity of the same church, are four others. But the principal characteristic of those at St. Nicholas', is the extremely high pitch of the stone roof, a peculiarity equally observable in the roof of the choir; and hence the following remarks on the part of Mr. Turner[113]:--"Here we have the exact counterpart of the Irish stone-roofed chapels, the most celebrated of which, that of Cormac in Cashel cathedral, appears, from all the drawings and descriptions I have seen of it, to be altogether a Norman building. Ledwich asserts that 'this chapel is truly Saxon, and was erected prior to the introduction of the Norman and Gothic styles.'[114] If we agree with him, we only obtain a proof, that there is no essential
