Shwezigon, the most prominent stupa is now located in Nyaung Oo. It was built by King Anawrahta who left it in an unfinished state and the pagoda was completed by his successor King Kyansittha. This golden pagoda is prototype and an ideal model of later Myanmar stupas. It is a solid, cylindrical structure resting on three square terraces and the best example of Bagan period which shows the high-point of Myanmar stupa architecture
