The loop hole is one of those architectural features found fixed to walls outside old houses. Donkeys or horses would be tied to the loop hole until the owner harnessed the beast for the day. https://365project.org/elza/extra-curricula/2021-05-31
Someone removed this particular loop from its original wall and placed on a pillar which made it possible for me to look through onto the field beyond. It made a nice frame for the farmer tilling his land.
