Get in touch with your spiritual side and offer up your own prayer at Sct. Pauls Church. Sit in quiet reflection outside for a few moments or ask if you're allowed to join the next service.
This house of prayer in Sønderborg is popular with many travelers, so put it on your to-do list. Don't think that's all there is to do here, though. There are a lot more attractions waiting for you to experience after Sct. Paul's Church. Sonderborg Castle, Augustenborg Palace, and Alsion are close by.
