Oude Kerk is Amsterdam's oldest building and it's right in the middle of the Red Light District. They often host photography exhibitions like World Press Photo, which makes for a fascinating contrast with the surroundings.

Check if it's Open Tower Day when you can climb the bell tower for incredible views over the old city. The church is typically open 10am-6pm daily, though hours vary for events, and entry is around €10. It's a peaceful break from the chaos of the Red Light District.
