Since crown prince Saliya married a Chandala girl, King Dutugamunu’s younger brother, Saddha Tissa was consecrated as King.[1] King Saddha Tissa continued the remaining work in Mahathupa.
During Saddha Tissa's reign, there was a major fire in the Lovamahapaya. The king subsequently reconstructed the Lowa Maha Paaya at one third of the cost with seven levels, two less than before.[1]
King Saddha Tissa built the Dighavapi vihara and the Duratissa reservoir.[1] The Duratissa reservoir has an embankment 3,400 feet (1,000 m) long and 14 feet (4.3 m) high. The top of the bank is 15 feet (4.6 m) wide. The reservoir has a capacity of 336 million cubic feet (9,500,000 m3) and a surface area of 1,230 acres (500 ha).[2]
After King Saddha Tissa’s death, Mahasangha supported the second son of the king, Thulatthana.
