The historical centre of Colombo is Fort Colombo (district 1). During the Dutch and British occupation this was an actual fort. Build to defend the colonising powers from any local forces. Fact is that the Portuguese started to develop this area. Later when the Dutch took over they developed this area. During the rule of the British the wall were torn down and this was made into a high end heart of the island with more British names and brands you could imagine. Although today the architecture is crumbling, it is still a reminder of colonial powers and their influences.
