The Maiden Tower is a 12th-century monument, situated in the heart of the Old City of Baku. Since 2001 it is a part of the UNESCO World Heritage List, also listed as Heritage in danger, after a destructive earthquake which happened in the recent years. The Tower also hosts a Museum, which displays artifacts, representing the history of Baku's Old City during the ages. This is actually a place of numerous myths and unsolved mystery, which has inspired a lot of the Azeris' folk tales and different pieces of art. The main unanswered question is about the character and purpose of the building. One of the most popular legends says that back in Zoroastrian times it was the home of a virgin girl, who saved Baku's people from slavery.
