Two places i went at first; Berlin & Strasbourg. Eventually i realized there's not that many "cathedrals" which hold a world record. I glimpsed at Chartres for awhile and typed "Tallest Churches" in google and BANG - Ulm came up, it was then a matter of finding the curvy river and put 3D buildings to confirm the orientation!
So, here's a much easier one (I guess!) - never been there myself, but i thought such a challenge would be fun to have. The planet is ours, might as well "see" it in all its tiny glory!
This shipping boat is parked and going "up" on that image.
1-- What is its "presumably right" destination?
2-- It will go through a Lake, near a big Island and underneath two bridges; name all four.
3-- It most probably went right by a city and will eventually reach another one; name both.
