In case you’re as clueless as we were when we suddenly found ourselves standing in front of this enormous thing, wondering what on earth it was: a graduation tower is basically a huge wooden structure filled with bundles of branches. Salt water trickles down through them, evaporating in the wind and making the air around it slightly salty, a bit like being by the sea.

I’d never heard of or seen anything like it before, and it really was a sight to behold. Definitely one of the highlights of our day trip to Lüneburg.
