The fence says “No Solicitors.” The crosses say “No Vampires.”
Vampire Solicitors are right out.
Now, if this were a church, the cross motif would make sense. But, this isn’t a church, or a cemetary, or a funeral home, or wedding chapel. it’s just an office building. Perhaps, you may reasonably suggest, it used to be one of those things. Perhaps so. Interestingly, the building’s neighbor has the same fence, sans crosses. These look as though they were just welded on. (Then again, how else would you attach them?) I suppose we’ll never know the real reason for the decor, but vamprophobia remains my favorite theory.
