The hill-range of Riṭigala is located about twenty-five miles south-east of Anurādhapura and eighteen miles north-east of Dam̆bulla. The range has numerous caves, rocks, ruins and inscriptions. Wickremasinghe describes four groups of inscriptions at different locations in the mountain range:
[1] Āṇḍiyā-kanda (east spur) – 10 cave-inscriptions.
[2] Karam̆bǟ-hīnna (north-west spur) – 2 cave-inscriptions (of which only one is described by Wickremasinghe).
[3] Nā-ulpata, also called Nā-arambädda-hīnna (west and south-west spur) – 1 cave-inscription; 4 rock-inscriptions (of which only three are described by Wickremasinghe).
[4] Vēväl-tänna (lower eastern spur) – 1 cave-inscription; 1 rock-inscription.
The cave [called] Mahāsudassana of Brother Sōṇa is established for the Buddhist priesthood from the four quarters.
