One location in England that is iconic is the local pub. Pub signs would be an object that is iconic. Most pubs in England have a sign that incorporates an image with the name. Although the green man image appears on some grotesques on churches and other places in the US, it is more of a thing in England.

The green man idea is ancient with pagan roots, but the image appears on churches in England. Pagan symbols were brought into the early Christian Church. They say the green man appears on churches to symbolise rebirth and resurrection.
As with this image on the pub sign, green men are often depicted with leaves around their face and sometimes acorns. Have a great week!
