On a wet and miserable day, I thought you might like a few mystery pics to be going on with but you may have to wait a while before I comment on your answers!
Yes, it s the Churchtown Cross, St Erth, a tall lantern-type crossmounted on a square base. On the head is a Christ figure, in relief within a wide border. On the back is a Latin cross within the border. It stands beside the shop in the centre of St Erth.
