The medieval Capital of ancient Sri Lanka, Polonnaruwa was a fortified city. What is now known in Polonnaruwa as the citadel was the fortified portion of the inner city within which the palace and other royal establishments were located. The chronicle Culavamsa claims that the city was surrounded by three moats and four fortified walls of receding height in the 12th century A.D. The excavated portions of the city justify the claims of the Culavamsa.
The architectural remains of the royal palaces and other establishments are very imposing and occupy a prominent position among the excavated ruins. One remarkable feature at Polonnaruwa is that its secular aspect was not so thoroughly and completely overshadowed by religious establishments as in Anuradhapura.
The Sacred city became World Heritage site on 1981.
