THE SACRED TERRACE
The Polonnaruwa Quadrangle: Vatadage, Gal Pota and More
A close look at Polonnaruwa's sacred terrace — the circular Vatadage, the Hatadage, the inscribed Gal Pota stone book, and the unusual stepped Satmahal Prasada.

The Quadrangle — known locally as the Dalada Maluwa, or Tooth Relic terrace — is a raised platform packed more densely with significant monuments than anywhere else at Polonnaruwa, reflecting its role as the city's religious centre rather than its administrative one. Sri Lanka's most sacred object, the tooth relic of the Buddha, was kept here during the Polonnaruwa period before later being moved on to Kandy, and the cluster of structures on the terrace — relic houses, image houses, an inscribed stone slab and a stepped shrine — all relate in some way to housing, protecting or honouring that relic.
The Vatadage's circular relic house
The Vatadage is the Quadrangle's centrepiece: a circular relic house built around a small central dagoba, ringed by stone pillars that likely once supported a wooden roof, with four seated Buddha images facing the cardinal directions. Its guardstones and the semicircular carved step-stones at its entrances are generally considered plainer than the more elaborate versions at Anuradhapura, reflecting a slightly later and more restrained regional style. Its construction is usually associated with Parakramabahu I's reign, with further work commonly attributed to Nissanka Malla shortly after, though the exact building sequence between the two isn't fully settled.
The Hatadage and its curious name
The Hatadage, another relic house on the terrace, is credited to King Nissanka Malla, who reigned shortly after Parakramabahu I. Its name is popularly explained two different ways — as the 'house of sixty relics' or as a building said to have been completed in just sixty hours — and while neither claim can really be verified against Nissanka Malla's own famously boastful inscriptions, the folk etymology is worth knowing because it's the story you'll hear on site. Structurally, it once held an image of the tooth relic during the Quadrangle's period as its guardian building.
The Gal Pota — a book carved in stone
Just beside the Hatadage lies the Gal Pota, the 'Stone Book' — a single massive granite slab, commissioned by Nissanka Malla, inscribed on its upper surface with a lengthy account of his reign and achievements. Sources commonly put the slab at roughly nine metres long and well over twenty tonnes, and local tradition holds it was hauled from a quarry near Mihintale, close to a hundred kilometres away — a claim that, if accurate, says as much about Nissanka Malla's appetite for grand gestures as the accompanying text does. It remains one of the largest ancient stone inscriptions in Sri Lanka.
The Satmahal Prasada's odd shape
Unlike anything else on the Quadrangle, the Satmahal Prasada is a stepped, tapering brick structure of, as its name suggests, roughly seven diminishing tiers, giving it a pyramid-like silhouette that stands apart from Sri Lanka's usual bell-shaped dagobas. Its resemblance to stepped Southeast Asian temple forms has led some scholars to suggest Khmer or other regional architectural influence, arriving via Polonnaruwa's trade and diplomatic contacts across the Bay of Bengal, though its precise origin and original function remain genuinely debated rather than settled fact. It's a small structure, easy to walk past, but one of the site's more architecturally unusual survivals.
The Quadrangle's monuments compared
Seen together rather than one at a time, the four monuments show how much religious and political business was concentrated on one compact terrace — relic-keeping, royal record-keeping and temple building all layered into the same small space within a generation or two of each other. Walking the Quadrangle slowly, monument by monument, does more to explain 12th-century Polonnaruwa than any other single stop on the site, since it compresses a reign and a half of royal ambition — two kings' worth of relic houses, inscriptions and shrines — into a plot barely a hundred metres across.
