This huge dagoba was the first built by Dutugemunu after he captured the city in the 2nd century BC. The story goes that Dutugemunu went to bathe in the tank, leaving his ornate sceptre implanted in the bank. When he emerged he found his sceptre, which contained a relic of the Buddha, impossible to pull out. Taking this as an auspicious sign, he had the dagoba built.
Mirisavatiya Dagoba is one of three very interesting sites that can be visited in a stroll or ride along the banks of the Tissa Wewa.
