Halshany or Holszany Castle is the ruined residence of the Sapieha magnate family in Halshany, Hrodna Voblast, Belarus. It used to be the seat of one of the largest land estates in the Grand Duchy of Lithuania.
The current structure was built about 1610 by Paweł Stefan Sapieha to replace an older castle of the Holszanski princely family, of whom Sapiehas were descendants and heirs.
Also known as the Black Castle, the residence formerly rivaled Mir Castle as the most elegant private château of the Grand Duchy of Lithuania. The name Black Castle in fact originally applies to a fictional building from a book by Uladzimir Karatkievich, which was loosely based on Halshany Castle.
