The Giritale tank (Sinhala; Sinhalese: ගිරිතලේ වැව) is a reservoir in Giritale and Minneriya in Sri Lanka. It was built by King Agbo II (608-618). It is believed that the tank was renovated by King Parakramabahu, the Great (1153–1186).[2] Later, it was subjected to renovation in 1905, 1942 and 1952 during colonial era.
Giritale Tank was considered as the deepest tank in Sri Lanka during the rule of medieval capital Polonnaruwa.[3]
