Polonnaruwa was Sri Lanka's capital for around 250 years after Anuradhapura fell, and its ruins survive in far better condition — carved Buddha statues, a royal palace, and irrigation reservoirs still used today spread across a compact, cyclable archaeological park.
Four Buddha images carved directly into a single granite outcrop in the 12th century, including a 14-metre reclining figure regarded as a masterpiece of Sinhalese sculpture.
The remains of King Parakramabahu I's seven-storey palace, with walls up to 3 metres thick still standing among the brick foundations.
Inscribed for its well-preserved medieval urban planning and religious monuments, detailed on UNESCO's World Heritage list.
Combine the ancient city tour with a stop at the nearby Medirigiriya vatadage or Wasgamuwa National Park.
