 The oldest graves are to the north of the church , which is unusual : ordinarily the southern part of the churchyard would be used first for burials , with the northern part remaining <unk> unless and until extra space for graves was required . The path between the road and the church has sunken , which may partly be explained by the medieval custom of burying the dead on top of each other . One author has suggested that the mound alongside the path might indicate that the church is located in the site of a Bronze Age settlement .
