Interesting! I'm a bit of a sceptic when it comes to churches on platforms being old. Unless the platform is a flattened barrow...

The Wirral is a fascinating place, at the mouth of the Mersey, "roadway" to the Peak District from the west. I was reading a webpage re the stones etc on Wirral, looks like there are a few left standing, and the sheer number suggests the whole area could have been fairly populated back in the BA.
