In Sinhalese, it is known as the 'watadage' and it is one of the finest examples of the sculptures and architecture of the Polonnaruwa Period. The quadrangle contains four seated statues of the Buddha surrounding the shrine in the middle with four entrances. Built during the reign of Great King Parakramabahu, or King Nissanka Malla, the complex was made to contain the sacred tooth relic of the Buddha. Although sections have been ravaged by time, some of the best-preserved examples of sculpture can be found here. The Sandakada Pahana (moonstone), depicts the sansaric journey of beings with many rebirths until they reach final enlightenment or Nibbana. The muragal were guard stones that depict various deities that protected the premises.
