At the southern end of the Quadrangle, the Thuparama Gedige is the smallest gedige (hollow Buddhist temple with thick walls) in Polonnaruwa, but is also one of the best: it's the only one with its roof intact, supported by corbel arch-style supports. The inner chamber is delightfully cool and contains four beautifully executed standing Bodhisattva statues.
The building's exterior shows a marked Hindu influence and is thought to date from the reign of Parakramabahu I.
