Polonnaruwa is Sri Lanka’s medieval capital and one of its most rewarding archaeological experiences – a remarkably well-preserved ancient city set beside a vast man-made reservoir, best explored by bicycle on a trail that moves through royal compounds, sacred temples, and the celebrated Gal Viharaya, where four colossal Buddha figures are carved directly into a granite face. The ruins are concentrated, accessible, and visually magnificent, with a parkland setting that makes the experience of moving through them genuinely pleasurable. One of the finest ancient cities in Asia.
