It's interesting to explore differing beliefs. A visit to Norre Uttrup Kirke is a superb way to learn about one of the local religions.
You'll be spoiled for sightseeing choice in Norresundby. Norre Uttrup Kirke is a great place to kick off here, but there are many other interesting places to experience. Aalborg Zoo, Budolfi Cathedral, and North Jutland Art Museum are near the house of prayer and will round out your day nicely.
