Plaque showing site of Castle of Dundee

Plaque showing site of Castle of Dundee is a castle, fort or tower in Dundee City, Scotland. Perhaps the castle walls fell and the stones scattered into other buildings, leaving only this small marker to prove the shape of what was lost. Maybe the plaque exists because memory needs a visible anchor when the architecture disappears. Imagine a guard standing at that spot, watching the river and the road, knowing the stone would one day become nobody's fact.
