Archaeologists from the Department of Archaeology, in collaboration with the University of Kelaniya and Australia's La Trobe University, have commenced high-precision excavations at the northeastern gate of Polonnaruwa's outer fortification wall and areas surrounding the famous Lotus Pond (Nelum Pokuna). The field excavation strategy follows groundbreaking aerial LiDAR (Light Detection and Ranging) surveys conducted across the Polonnaruwa World Heritage site, which revealed previously unrecorded buried structures, ancient road grids, and residential mound formations hidden beneath dense jungle canopy. Initial trench excavations at the northeastern gate have uncovered intact granite wall foundations, ancient guardhouse masonry, and water channel conduits dating back to the reign of King Parakramabahu I (1153–1186 CE). The joint research team is utilizing 3D digital photogrammetry and soil stratigraphy analysis to reconstruct the spatial organization of the medieval city's outer defense perimeter and urban layout. Central Cultural Fund (CCF) directors emphasized that the findings will significantly enrich public understanding of medieval Sri Lankan urban planning while providing critical baseline data for ongoing site preservation.
