Sandagiriya village which resembles an arboraceous of dense ranges of mountains, situated 42 km away from Balangoda town comprised of Meda Korale Helapalla area adjacent to veligepola, is today introduced as “Katupath Oya” village.
In pursue of the age old ruins that dispersed in a large area around 36 sq km, it is clear that sandagiriya might have been a magalopolis and a kingdom in bygone era. The ancient village, area names, reservoirs and dams, sanctuaries, stupa, Bodhi-ghara, palaces and parapets are the precise evidences that mirror the concealed metropolis in laps of time.
In Mahawanshaya there is a mention about a prince called “Vikrama Pandya” who has kinged ancient “Kalathiththapura” alias Kalthota kingdom in sandagiriya area.
When enquiring information on remains in that area like ruins and inscriptions of Budugala, Piyangiri caves, piyangiri brook, and residual tiles and bricks, edifices, moonstones, balustrades, lithographed walls, monoliths, stairs, parapets, stretch of fields, places of worship, and reservoirs it is obvious that this region has been a kingdom in far history.
Sandagiriya which was a fertile and luxuriant capital of dense population existed in the name “Sandagana Nuwara” in around 200 B.C. Ruins of the palace complex where the sacred tooth relic was once enshrined is considered as the most significant part in Sandagiriya.
In the days of yore this area might have been abundant in red sandal wood (Pterocarpus santalinus) and sandle – wood (Santalum album) that are remained over even today.Flora like sandle – wood, madara (Cluytia collina) and kalunika ( a species of vitex) in Mahawalathenna adjacent to sandagiriya remain even by this time.
When considering the fact that Balangoda Bellan Bandi Pelessa where anthropoids of fossil age (Stone Age) who belong to a type of Homo sapiens in Sri Lanka lived tousands of years ago is located about 16km away to the right direction of Sandagiriya area which is also called as “Chandra Girl”. This area can be regarded as a significant quarter where the former colonies is Sri Lanka have been originated. It seems that arboraceous, uninhabited Sandagiriya that had been devastated in lapse of time has been repopulated in the middle of 19th century.
