Aghperig monastery (variously Aghperga, St. Aghprig Monastery (Աղբերկայ or Ս. Աղբերիկ Վանք)), also known as Beyaz Kilise, is a medieval Armenian monastic complex in the Sasun Mountains of eastern Turkey. It is located 56 kilometres West of Lake Van in the north of the Sassun mountains in the Sason district in the province of Bitlis. The monastery was built above a natural spring from where it gets its name Sourp Aghperig (Holy Spring).
