Banyusumurup is a village southeast of Imogiri in Southern Central Java or Yogyakarta region.
The village was acknowledged as a 'kris making' location at some stages in the 20th century.
The Graveyard is part of the Imogiri Royal Graveyard complex, traditionally associated with being the 'outcast' graveyard of those who fell out of favour with rulers - in most cases in the 17th and 18th centuries.
