No doubt an engineering and design marvel in Reykjavik, Iceland. Hallgrimsgirkja. Have seen it 3 times and been inside once. Not the best photo, I would say, but if something is going to fit into your theme, it's this.

Actually, take this one for the contest. The first one is literal shit, not even straight 😄

Whoooah that's an amazing photo.
Heh, thanks, second one really looks better!
Indeed! It captures the size of the thing so much more.
