Is it the main church in Willenhall? If so there was a church on the site dating from 700 years ago. It looks like red sandstone to me - there's a quarry for that at Codsall and the exterior of the existing church was clad with stone from there along with several other churches.
Saxon/maybe Roman pillar outside St Peters,W-ton and two other Saxon cross bases in the city.
Could also be something from a Victoriam Del-boy's mum's grave perhaps?
