I have a normal route that I did for many years, about 50 miles and visiting 32 churches. I would agree Churches were a key focal point for the local community which saw them embody the community's history. The memorials, art, architecture and decoration all reflect that history and even current thinking.
Of course some have pieces of art that are strangely in keeping but out of place either by being grander than expected or by being less than expected but clearly highly thought of. All Saints Rettendon has this amazing marble memorial to Edmund Humphrey which was a vanity project. It is an amazing bit of sculpture in marble. It is rather unexpected in a parish church but it is also rather spectacular.
