Free to enter the Church without any tickets but it's unclear what time it's open to public. When I was there, the sign read Opens at 1pm, so I left for lunch and returned later, the sign says Close at 2pm. I was there just 15 mins before, with enough time to snap a few pictures before it closed. Turned out that's because there's a concert that night, so the church is closed earlier than the usual 3.30pm.

Stepping into the church, you first see the altar then you realize the seats are turned the other way round and when you look behind you, you are wowed by the huge wooden organ that appears to be hanging from the ceiling. The organ is supported by 2 elephants, which are to signify the powers of Denmark that once stretched to India. This, I learnt from a video inside the Tower later, so pro tip: climb the tower first as the video talks about a few interesting points in the church to look out for. A pity by the time I finished the climb, the church has closed.

The church has a Tower at the top, with a spiral staircase that gives a bird's eye view of the city and beyond. Inside the tower, you find the bell, carillon and some broken pieces of decor here and there behind gated space. To climb the tower will require advance reservations via their website with the CPH Discover Card but it seems there is a quota for it cause when I arrived early and wanted to change my slot to an earlier one, the staff said there's still availability for 1.30pm, yet when I went online, it says sold out under the Copenhagen card option.

On one of the levels, there's a small room with a video description of the history of the church and the tower. One should watch this before the ascend and visit the church after.

The steps are pretty narrow and while I didn't count the number of steps, it was quite a workout getting up there. Once you are there, the views are worth it! The winds are so strong at some point I felt I was going to be blown over but the metal railings gave some sense of security. At the end point, the step is just sufficient space for 1 foot. And if you thought going up was tiring, coming down (the same way) was even tougher. The entire climb took me about 45 mins, including some waiting time to take photos at the tip.
