Sri Lanka Holidays Cultural Attractions nearby Gal Oya National Park
Location: some thirteen miles east of Ampara
Ruins: 35 archaeological sites including the site of the ancient Buddhist shrine of Dighavapi hallowed by the visit of Lord Buddha.
Restoration: very slow in view of limited funds at the Department of Archaeology, Sri Lanka
Devastation: very quick. The area declared under the Archaeological department is only four hundred yards in radius of each site leaving the other areas unprotected under the Antiquities Ordinance No. 9 of 1940. As a result of this pathetic situation there has been a great deal of illegal excavations, sand mining and encroachments in the open areas.
Location: 8km from the town of Ampara
Ruins: Buddhangala hermitage of about 1280 acres and Girikumbhila Vihara, where the Venerable Arhath Mahinda’s relics are enshrined, is located to the west of the hermitage
Restoration: following a century of negligence, the ancient site is being restored by Buddhist Monk Rev. Kalutara Dhammananda Thero.
The landscape: streams of water flows over and around the boulders of the ancient rock hermitage.
The highest point of the rock is about 150 Meters. On ascending to the top of it, one can see the Gal-Oya valley on one side. To the south are the Inginiyagala, Vadinagala and the Govinda Pabbatha which was once the realm of Buwanekabahu Äpa
