The names Marienburg (help·info) or Frauenburg were given to many towns in German-speaking countries in the Middle Ages. The names usually originated in the construction of a fortified (hence -burg) chapel, church, or monastery dedicated to the Virgin Mary, also descriptively called Frau (woman, wife). Ex. Marienburg Abbey:[1]. There are many fortresses, castles, and towns with the name Marienburg, such as:
