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.

The tower formed a separate building, with quoins complete from the ground, and nave, chancel, and transepts, instead of combining to support it, were mere excrescences from it, entered by arches in its walls.

The inner or upper half of each of these four quoins forms the bases of two triangles, one at each side, making eight in all, which are called "star facets," and the inner lines of these eight star facets form the boundary of the top of the stone, called the "table."
