In addition to the Upper Castle, or as it is called today, Lutsk Castle or Lubart Castle, city also had the Lower Castle. There were 8 towers in its mighty walls – 4 wooden and 4 stone. Nowadays, only one of them has survived – the Chаrtorysky Tower, named after its foundrers. Tower was built in the 15th century and has remained unchanged until today. Due to this, it continues to attract tourists. There is a defensive wall adjoining the tower, decorated with a Gothic and diamond-shaped ornament of brick.
