Colombo | Sri Lanka

Colombo serves as the commercial capital and largest city of Sri Lanka, situated on the island's western coast. It functions as the primary hub for the country’s financial, corporate, and administrative sectors, and possesses one of the busiest deep-water ports in South Asia.

Historical Timeline

Originating as a small port for Roman, Arab, and Chinese traders, Colombo was fortified by the Portuguese in 1517. It subsequently fell to the Dutch in 1656 and the British in 1796. Following independence in 1948, the city underwent rapid urbanization. In 1982, the administrative capital was moved to the nearby suburb of Sri Jayawardenepura Kotte, though Colombo remains the de facto executive and judicial center.

Demographics & Population

The city proper has a population of approximately 600,000, while the greater metropolitan area exceeds 5.6 million. The demographic is multi-ethnic and multi-religious, comprising Sinhalese, Sri Lankan Tamils, Moors, and Burghers.

The city is divided into 15 numbered postal districts.

Facts & Legends

Legend says the name "Colombo" is derived from the Sinhalese Kola-amba-thota, meaning "Harbor with leafy mango trees." A geographic fact: The city is built on a series of canals and lagoons, many of which were expanded by the Dutch for transport. Historically, Colombo was the primary gateway for the global cinnamon trade, which once grew wild in the area now known as Cinnamon Gardens.
