This really should be a must-do experience in Copenhagen. The name of the church in English is…read moreChurch of Our Savior, but most Americans call it "that spiral church" which seems to resonate with just about everyone.
Two tips: First, skip this if you don't like heights because if you don't feel comfortable with outside steps, it's not worth going to (although it's a very cool church to look at). Secondly, be SURE you get advance tickets at least one day in advance. This is easy to do on the Internet, but critical.
Fortunately for me, this church was only a 10 minute walk from my hotel. Also, fortunately, I love climbing to the top of churches. The church was built in 1752 and is stunning. The tower has 400 steps; the first 250 steps are inside the tower on steep, narrow, old wooden stairs, and the final 150 steps on the outside, wrapping around the spire on a winding, narrow (but two people can easily pass each other), spiral staircase. Please note that I'm 70 years old, but still didn't have any issues, except for a few quick rest stops on the way up.
I didn't have time to explore the inside of the church, but I thoroughly enjoyed walking in the neighborhood surrounding the church (just about 10 -15 minute walk from Central Copenhagen) and the magnificent view from the outside of the church.
