St. Mary's Church
This church began its construction in the 13th century, at the foot of the Sparrenburg fortress. The church gained its final appearance in the 15th century and is most noted by its two 78 meter tall gothic spires. These spires were replaced after the originals were destroyed in the Second World War. The church houses a 15th-century altarpiece done by an unknown artist that is considered one of the most valuable pieces of medieval art in Germany; two of its fragments are kept in the New York Metropolitan Museum of Art.
