Sec. 25. At Worth, however, in spite of the dignity of the lateral arches, the chapels are still porch-like excrescences, larger in scale than usual, but lower in elevation than the nave. In elevation their transept-like appearance is less noticeable than on plan. Moreover, the length of the nave remains unbroken from west wall to chancel arch: no central space is marked off to which these transeptal projections give emphasis. Nevertheless, a suggestion of an intermediate space between nave and chancel is given; and this space is definitely marked in the plans of churches which may be quite as early in date as Worth--_i.e._ about the first half of the eleventh century--by the admission of a tower between nave and chancel. The eastern part of the walls of the nave at St Mary's in Dover Castle are continued upwards as a tower, with small rectangular chapels projecting from the sides of the ground floor. Externally, no division between the tower and nave is noticeable; but, inside the church, in addition to the chancel arch and the arches into the chapels, a fourth arch is pierced in the western wall of the tower, and so an intermediate space between tower and nave is effectually created. At Breamore in Hants, a further step is taken. The tower space, between nave and chancel, is of the same width as the nave; but, in addition to the necessary internal division, an external division is also marked by the quoins of the tower, which are complete to the ground. Only one chapel remains at Breamore, on the south of the tower, entered by a narrow Saxon archway; but there was originally another on the north.
