The Vatadage is the architectural masterpiece of the Quadrangle and the most photographed building in Polonnaruwa. A circular reliquary shrine, it consists of two concentric stone terraces with finely carved moonstones, guardstones and balustrades; four seated Buddha statues face out from the inner platform towards the cardinal points; the centre once held a stupa.
The proportions and workmanship are exceptional even for Polonnaruwa, which says a great deal. The whole structure was once roofed, probably in timber and tile, though only the stone foundations and column stumps survive. Climb the steps and walk a slow circuit around the platform; the carving of the doorways and moonstones repays a careful look.
