The history of Moratuwa is closely intertwined with the colonial past and cultural development of the western coast of Sri Lanka. Although the city was not an ancient capital, the first written mentions of it appear as early as the 15th century in the poem "Kokila Sandesaya," testifying to its centuries-old history. There is a theory that the name "Moratuwa" originates from the Sinhala "Mura Atuwa," which means "watchtower," indicating the settlement's strategic importance in the past.
Key factors in Moratuwa's emergence were its geographical location and trade. Situated on the shores of the Indian Ocean south of Colombo and surrounded by water on three sides, including the large Bolgoda Lake, the city became an important commercial and administrative center during Dutch and British rule. Its port played a significant role in trade links, and the proximity to water fostered the development of the fishing industry.
From early times, Moratuwa was renowned for its economic and cultural distinctiveness. The city became a center for traditional crafts, primarily woodworking and furniture manufacturing. The skill of local carpenters and woodcarvers is known throughout the country, with their traditions passed down from generation to generation. Beyond its crafts, the city is also known as a center of Christian missionary activity during the colonial era, which left a legacy of numerous churches and a strong educational heritage. Moratuwa has also gifted the country many famous musicians and artists, securing its status as a culturally significant city.
