Tomb of King Sitawaka Rajasinghe (සීතාවක පලමුවන රාජසිංහ සොහොන) is a historical site located on the Avissawella-Amithrigala road, close to the main road. King Rajasinghe I was a significant figure in Sri Lanka's history; Born as Tikiri Bandara, he led several battles against his brother-in-law, Veediye Bandara, ultimately earning the title Rajasinghe, the Lion King. One of his notable achievements was the “Bloody battle of Mulleriyawa” against the Portuguese army. Despite being equipped with more advanced firepower, the Portuguese were defeated by the Sinhalese army using their ancient fighting method called “Angam Pora”. The vast paddy field in Mulleriyawa reportedly turned red with the blood of the fallen Portuguese soldiers. Unfortunately, discontent among the Buddhist public and prelates contributed to the downfall of the Seethawaka kingdom. King Rajasinghe razed many Buddhist religious sites under the advice of his chief adviser, Aritta Kivendu, who converted to Hinduism. His last battle was with Konappu Bandara, who aimed to free the Kandyan Kingdom from Seethawaka. At the decisive battle at Balana, Rajasinghe's troops suffered defeat, and he retreated to the royal park at Pethangoda. Legend has it that he was struck by a fatal bamboo splinter in the foot, although this story remains subject to debate.
