The Ancient City of Polonnaruwa was Sri Lanka’s second historic capital and flourished as a centre of political power, culture, and innovation during the 12th century. Rising to prominence after the decline of Anuradhapura, the city reached its zenith under King Parakramabahu I, who transformed it into a well-planned garden city with monumental architecture and advanced water management systems. Polonnaruwa is renowned for its royal palaces, Buddhist temples, stupas, monasteries, and Brahmanic monuments from the Chola period, reflecting diverse cultural influences and refined stone craftsmanship. The iconic Gal Vihara rock sculptures stand as outstanding examples of artistic and religious expression. Its extensive irrigation networks, including massive reservoirs and canals, demonstrate exceptional engineering knowledge and sustainable urban planning. Together, these remains represent the height of medieval Sinhalese civilization and its enduring cultural and technological achievements.
