In France, the fashion in doorknockers seems to run less to lions than to hands. Actually, this set includes ones seen in Ludlow, Bishops Castle, and one in Shottery before and after the door it was on had a fresh coat of paint.
Not a doorknocker, but definitely French, this was one of the lampstands in the restaurant of the Hotel CroMagnon in les Eyzies. The village is at the centre of a region with numerous prehistoric sites, with a regional gastronomy centring on le canard.
