Every monastery has a dagoba. Ruwanweliseya is the dagoba of Maha Vihara. It was built by a Sinhalese hero king Dutugemunu in the 2nd century B.C. The architect ingeniously combined the Buddhist philosophy in the architectural conception. He conceived this as a bubble of milk: representing life, which will burst in no time just like the fragility of our lives. Its dome represents the vastness of the doctrine; the four facets of the box oh top represents the four noble truths. The concentric rings thereafter indicate the noble eightfold path that leads man to illumination. The illumination: the whole truth is light and transparent like the rock crystal at the pinnacle. The 1956's restoration curb on the dome is much to the chagrin of the purists: which looks flatter than bubbly.
