Somewhere in my slide collection is a pic of a similar thorn in a monstrance (sp? usage?) which was in the sacristy of the cathedral in Regensburg, Germany. Perhaps someone here saw the same one?
No way of knowing if it’s real— it was interestingly ancient enough had it merely dated from the days when Charlemagne would visit the city.
My own track had been stopped swinging around a corner where the building facing the street had been "cut back" to allow room for a track ~ either an APC or tank ~ to pass easily without knocking more holes in the building.
We were allowed to buy icecream and so forth but I imagine if I'd known about the thorn the CO'd given me a 1 hour pass to go look at it.
Darned! Been through that town several times too.
