Looking down one of the tunnels at the historic duck decoy at Boarstall.

Two children walking along a woodland path. Running alongside them is a netted tunnel over a timber lined channel which is part of the duck decoy structure.

Day 22's #ArchaeologyAdvent is a tunnel entrance, rather than a door & is part of the 17th century #Boarstall duck decoy. Duck decoys for catching waterfowl were once a common sight on rural estates; today, there are only a handful remaining.
