Climb to the heavens, literally, at the Church of Our Saviour in Copenhagen. With its serpentine spire that twists skywards, this baroque beauty is not just a place of worship but a challenge to those who dare ascend its 400 steps. The reward? Breathtaking views of Copenhagen that will make your Instagram followers green with envy.

Best time/season to visit:
Late spring to early autumn offers the perfect weather for climbing the tower and enjoying the panoramic views without the chill of the Danish winter biting at your heels.
