The first phase of a groundbreaking survey exploring the urbanization of Polonnaruwa during its reign, a period renowned for its archaeological significance and attraction to both local and foreign tourists, commenced last March. Using ground-penetrating radar, the survey focused on the vacant land behind the Parakramabahu Palace, the council hall, and the city’s north gate. This initial investigation uncovered evidence of brick walls and ponds buried beneath the surface.
The survey’s second phase, now underway with the collaboration of the University of Kelaniya, an Australian university, the Department of Archaeology, and the Central Cultural Fund, has employed LIDAR technology and drones to reveal even more fascinating insights. Among these findings is a garden complex featuring four ponds, reminiscent of the design at Sigiriya, along with associated pathways and roads hidden beneath the earth.
Professor Krishantha Gunawardena of the Department of Archaeology at the University of Kelaniya commented on these discoveries, highlighting the use of LIDAR technology in Polonnaruwa for the first time. The surveys indicate the presence of a garden about a meter below ground, and additional findings suggest the city extended as a large, complex urban area.
Significantly, the discovery of Chinese coins, pottery, gold, and mica-containing sherds within the site further corroborates the notion of robust international trade relations between Polonnaruwa and China during this period. Professor Gunawardena emphasized that the evidence points to human settlements dating back to the Anuradhapura period and confirms strong trade connections between Polonnaruwa’s rulers and China.
As excavation continues, samples of the archaeologically significant materials found in Polonnaruwa will be sent for dating, promising further revelations about the royal period. The findings strongly suggest that the kings who ruled Polonnaruwa towards the end of the 10th century adopted Sigiri garden techniques in the region. However, more analysis is needed to establish a definitive timeline, according to Professor Gunawardena.
