Rajaveliya, Poojavaliya and the Galpotha inscription itself mention that it was built in sixty hours. Since the Sinhalese word Hata means sixty and Dage means relic shrine, it is possible that the structure was named Hatadage to commemorate this feat. Another theory is that it is so named because it held sixty relics. Despite having built many structures, Nissanka Malla's major intention was to outdo the works of Parakramabahu I. He also built a statue of himself. Military (1153–1186) Parakramabahu organized the military of the kingdom. There were auxiliary forces made up mostly of other Buddhist ethnicities. Ground forces There were several branches of the ground forces of Polonnaruwa of Parakramabahu. The Culawamsa suggests that the strength may have been as many as 100,000 during the 1140s prior to the first battle of Rajarata.
