Historical sources about the castle are not well researched; the name Flis castle arises from the former owner. According to a fairy tale it should have come into being owing to two enemy brothers. They quarrelled so badly that one of them moved to a valley and built here a new castle building. The hostility between them wasn’t finished with that. In 1443 they should have shot each other from their castles. The ending is in spite of the legend somehow impossible as people didn’t have such precise weapons at that time. It is more likely that they killed each other in one of the fights that they had. The owner of the manor house was undoubtedly the Salzburg archdiocese; however it was managed by the Rajhenburg masters. The today’s image is from 17th century. In Brestanica it is well provided for the period of 2nd world; that time caused the Slovenians many hardships. A monument under the castle is dedicated to all exiles; there is a memorial plaque on the former castle outbuilding, there is another memorial plaque built into the stone under the castle and dedicated to exiles and Slovenian patriotic clergymen.
