The Columns of Gediminas or Pillars of Gediminas (Lithuanian: Gediminaičių stulpai, lit. 'Pillars of the Gediminids'; Belarusian: Калюмны, romanized: Kaliumny, 'Columns') are one of the earliest symbols of Lithuania and its historical coats of arms. They were used in the Grand Duchy of Lithuania, initially as a rulers' personal insignia, a state symbol, and later as a part of heraldic signs of leading aristocracy.
