About Colombo

Colombo (Sinhala: කොළඹ, Tamil: கொழும்பு) is the largest city and commercial capital of Sri Lanka, and still perceived by many as the capital though the suburb of Sri Jayawardenepura Kotte is now the official capital. Just like any other big South Asian city, Colombo is congested, noisy, busy, and vibrant with a mixture of modern life and colonial architecture. It is the financial centre of the island and a popular tourist destination.
