Colombo is the largest city and the commercial capital of Sri Lanka. It is located on the west coast of the island and has a population of around 647,100. The city has a long and rich history, having been a major port and trading hub since the 5th century BC.
The city was first settled by the Portuguese in 1505, and was later taken over by the Dutch in 1656. The British then took control of the city in 1796, and it remained under British rule until Sri Lanka gained independence in 1948. During this period, Colombo was transformed into a modern city, with the construction of many new buildings and infrastructure.
Today, Colombo is a vibrant and bustling city, with a mix of modern and colonial architecture. It is home to many cultural attractions, including the National Museum, the Dutch Period Museum, and the Colombo Zoo. The city is also a major financial and business hub, and is home to many international companies.
