Monoliths are really having a moment, aren’t they? A “mysterious” monolith that appeared in front of a Pittsburgh candy shop has been replaced after the original 10-foot structure was stolen on Saturday morning. But these particular monoliths differ from similar-looking finds that popped up in Utah or Romania or California or England, in that there was no initial mystery as to where they came from.These monoliths were commissioned by the owner of the candy shop himself.
