Colombo means "heaven of the sea" in the local Sinhari language. As early as the 8th century AD, Arab merchants were already doing business here. In the 12th century, Colombo had begun to take shape and was called Kalambu. Since the 16th century, Colombo was successively occupied by Portugal, the Netherlands and the British. As Colombo is located between Europe, India and the Far East, passing ships from Oceania to Europe have to pass through here, therefore, Colombo has gradually developed into a large port for international merchant ships.
