An interesting feature. The only other multiple cross I've seen was at Les Cinq Croix, in Les Loges Marchis, a small village in Normandy, France.
I wonder if they are a common occurrence.

Interesting place.

Nicely captured.

Very nicely captured Alex.    If the three crosses date back to 1500 as Google seems to think then they are really well preserved.  

Beautiful sign and well captured!
