Top Architecture in Cologne

Do yourself a favor and visit around 9 AM when it opens. It was way less crowded and I could really soak in the beauty without dodging a ton of tourists.

Try to catch one of the choral services if you can; it was such a beautiful experience and absolutely free! A perfect way to enjoy the acoustics of the cathedral.

If you're on a budget, skip the audio guide. I found plenty of info online and through the pamphlet they give. My advice is to save those euros for a nice bratwurst instead!

Bring a good camera or your phone charged. The intricate details on the outside and inside are just stunning. You won’t want to miss capturing those, trust me.
