One of most beautiful pagoda I've visited in Bagan is the Sulamani Temple. No wonder this pagoda is often called the “Crowning Jewel”.
Sulamani was built in 1181 and features two storeys standing on broad terraces assembled to create a pyramid effect. The brickwork throughout is considered some of the best in Bagan.
Once you venture inside you find corridors containing frescoes and murals from various eras. They depict scenes from the life of the Buddha as well as various mythological animals like Naga snakes and Makara sea creatures. You can just see one such painting behind the Buddha here.
