The mystery of England's sinking churches



English parish churches, if they have been there for any length of time as most of them have, tend to display a strange characteristic, which is that they seem to be sinking into the ground. Quite often the lowest course of stones appears to be a couple of feet below the level of the surrounding churchyard.

However, this is not because the church builders did not set the foundations properly, or that they regularly chose to build on soft ground into which the structure would sink over time. The fact is that the surrounding land has risen, and not that the church has sunk.

The reason for this is that churchyards are where people from the surrounding village have been buried for century after century. It is not all that long ago that the only legal way of disposing of a dead body was to bury it (cremation was first legalised in the United Kingdom in 1902, although the practice had started in the late 19th century). Burials could only take place in consecrated ground, and that meant the village churchyard.

However, churchyards were limited in area, which meant that space for burials was at a premium. The same piece of ground would therefore be re-dug for fresh burials several times over. Bones do not always decay completely – it depends on the acidity of the soil – so many burials took place on top of the bones of previous ones. Over time, layer upon layer of human remains, as well as the action of repeated digging, pushed the land surface higher and higher.

In a parish with a steady average population of 300 people, one might expect around a thousand adults to die every century. However, with child mortality being what it was in the past, there would have been many more than that number of burials. In a churchyard that was first laid out in the 10th or 11th century, the number of times that the gravediggers got to work between then and now could have been as many as 20,000, possibly even more.

It is little wonder that many churchyards seem to be swallowing their churches!
