St. Marienkirche
This enormous church is the largest of Stralsund's three redbrick Gothic churches. With 4,000 pipes and intricate decorative figures, the magnificent 17th-century Stellwagen organ (played only during Sunday services) is a delight to see and hear. The view from the church tower of Stralsund's old city center is well worth climbing the 349 steps. However, during church services at 10 am on Sunday, the sanctuary is closed to visitors who are not attending the services.
