Mahasen’s Palace and Eth Pokuna

A five-band carved stone doorstep, meant to be walked over rather than admired from a distance, is now considered the finest surviving example of its kind anywhere in Sri Lanka.

It’s a strange twist of history that Anuradhapura’s most celebrated single piece of stone carving isn’t a statue or a relief on a temple wall, it’s a doorstep, a semicircular slab called a moonstone, designed to be walked over by monks entering a now-vanished chapter house.

A Doormat Considered a Masterpiece

Little survives of Mahasen’s Palace today beyond a scattering of pillars and foundation stones, not enough to reconstruct any clear sense of the building’s original scale or appearance. What has survived, and drawn art historians and casual visitors alike for generations, is a single carved stone slab: the moonstone (sandakada pahana) marking the entrance, widely regarded as the finest and best-preserved example of this distinctly Sri Lankan architectural feature found anywhere on the island.

Moonstones traditionally sat at the base of staircases leading into ancient religious buildings and some royal palaces across Sri Lanka, functioning simultaneously as a practical doorstep and as a carefully composed piece of religious symbolism, meant to be walked over rather than simply admired, a detail that gives the genre a genuinely unusual relationship between sacred art and everyday physical use.

Five Bands, One Journey

The Mahasen’s Palace moonstone is carved with five concentric bands, each layer said to represent a different stage on the soul’s journey toward nirvana, culminating in a central lotus motif symbolising purity and enlightenment at the heart of the design. An outer band of flames frames the composition, while a procession of four different animals, generally interpreted as representing the cycle of birth, old age, sickness and death, circles the design at another level, making the moonstone a genuinely dense piece of Buddhist teaching compressed into a single carved stone.

Eth Pokuna, the Elephant Pond

A short distance from Mahasen’s Palace lies Eth Pokuna, or Elephant Pond, built in the 3rd century CE southwest of the Abhayagiri stupa and recognised as the largest ancient man-made pond anywhere in Anuradhapura. Its scale reflects the substantial water management needs of a monastic community that, at its peak, housed thousands of monks, underscoring just how much practical infrastructure supported the religious life visible in the site’s more famous stupas and shrines.

A second moonstone, similarly noteworthy though generally considered slightly less refined than the Mahasen’s Palace example, was also discovered a short distance away at what’s known as the Queen’s Palace, giving the wider Abhayagiri complex two genuinely significant examples of this distinctive carving tradition within easy walking distance of one another.

Visiting Tips

Spend real time studying the moonstone’s five carved bands, a genuinely rewarding piece of Buddhist symbolism rendered in stone.
Combine with a visit to Ratna Prasada and the Abhayagiri Dagoba, both within the same monastic complex.
Walk to Eth Pokuna afterward to appreciate the scale of ancient monastic water infrastructure.
Bring a guide or reference material to fully appreciate the moonstone’s symbolic layers, easy to miss without context.
