The town in Scotland nearest to where I live, Burntisland, has docks and they have a huge crane there - at Xmas the company puts a Christmas tree on top of the crane about 65m or so up.

It's quite bizarre as when it's dark (and days are quite short in Scotland at Xmas) you can't see the crane just this lit up Xmas tree hanging in space above the town. It's very cool.
