Batadomba Lena is located in a highland called “Vithana Kanda” within a short distance from Ekneligoda area that belongs to Kuruvita Korale. It can be reached from the Kuruwita-Sripada road starting from Ratnapura- Colombo highway. This is centered in between 6046` to 607` latitudes and 80023` to 80024` longitudes belonging to low-country in wet-zone spread from 1400 m to 1500 m of contour lines. Also this historical den is located 234 m above sea level. The surrounding land of Batadomba Lena that spans over about 35 acres has been promulgated as an archaeological reserve.
The foremost primordial fossil of modern anthropoid in South Asia has been discovered in this cavern. The first excavation was done in Batadomba Lena in 1938 by Dr. P.E.P. Daraniyagala who was then the Director of Museum of Sri Lanka Museum Department. Thereafter, this place of history has undergone several excavations conducted by the Department of Archaeology based on the information given by villagers. Until then this cavern was abandon for the wild to invade.
Both “Maha Lena” (large cave) and “Kuda Lena” (small cave) are located on a gigantic rock that would rise about 78 m tall. As a whole, this rock can be considered as a fusion of a stretch of caves that spans for about 500 m and the two caves in two extremities are larger than the others. The cavern at right side is the largest of all. “Maha Lena” would measure about 28 m long, 12 m wide at face and 8 m wide at back. “Kuda Lena” is only 9 m long and 9.4 m wide.
“Maha Lena” is spacious enough to shade easily little more or less than 1000 people at once. Through an excavation a fossilized skeleton of a woman and several tools which were used by people lived in the Stone Age have been discovered at the left wall of “Kuda Lena”. The excavations done in 1979, 1980 and 1981 were directed by Dr. S.U. Daraniyagala, the Assistant Commissioner of Archaeology at that time.
