Tivoli Gardens was a total treat to see.
It's one of the oldest amusement parks in the world, and they uniquely have kept the rides rather old-fashioned looking, but stylized. Very steampunk. It's a place to take a nice stroll, admire the gardens and the beautiful lights that flicker on once the sun finally goes down.
They have fireworks on the weekends, but since it's light here until late, they don't start until midnight. While standing around in the cold waiting for them to start was a bit unpleasant, it was worth it. I do love a good fireworks show, and they synch their to music.
