Sacred Quadrangle-Polonnaruwa,Sri Lanka.
Polonnaruwa was Sri Lanka’s second capital and became Sri Lanka’s royal medieval capital in 1073. It remained Sri Lanka’s capital until the late 13th century, but became increasingly susceptible to Chola invasions and it became lost to the jungle once more as the capital drifted south-west. Today, the ancient city’s ruins remain in remarkably good nick, and are a fascinating site to visit.
