Reconnect with your spiritual side and mingle with worshippers at Paulus Church. Quietly reflect outside for a while or find out if you are allowed to join the next service.
If you're staying a while in Grünerløkka, Paulus Church is a good place to kick off your sightseeing. This house of prayer is one of many attractions worth checking out here. Oslo Opera House, Karl Johan Gate, and Viking Ship Museum are also waiting to be explored nearby.
