Half moon stone
Ruins located in Anuradhapura
Sandakada pahana, also known as Moon-stone, is a unique feature of the Sinhalese architecture of ancient Sri Lanka.
It is an elaborately carved semi-circular stone slab, usually placed at the bottom of staircases and entrances.
First seen in the latter stage of the Anuradhapura period, the sandakada pahana evolved through the Polonnaruwa, Gampola and Kandy period. According to historians, the sandakada pahana symbolises the cycle of Samsara in Buddhism.
