Beneath the organ gallery you can see the painting of Great Duke Friedrich Franz I. von Mecklenburg, the founder of the first German seaside health resort in Heiligendamm in the year 1793. The marble sarcophagus serves as final resting place for Princess Feodora von Reuß (died 1918), wife of Duke Adolf Friedrich von Mecklenburg. Next to it is the tomb stone of Duke Pribislav (died 1179) thought to have been mistakenly placed on top of the grave of Duke Heinrich I von Mecklenburg (died 1302) sometime during the 19th century.
