These--if ancient--seem to be invariably on (not merely alongside) a ley, and in many cases are at the crossing of two leys, thus appropriating the sighting point to a new use. A ley often passes through a tump adjacent to the church, and a cross ley through both church and tump. In other cases a mark stone site became the churchyard cross, and a cross ley comes through both church and cross. In many cases one of the leys went through the tower only, and it is possible that tower and steeple were built to be used as sighting points, although on the other hand a large church did in fact block the road. I will make no surmises on these interesting points. The sighting system may have been in decay or the tracks abandoned when the churches were first built on the sighting points. I do not think it probable that leys were made to provide sites for churches.
