The natural harbour of Galle was famous as far back as 1400 BC. At that time it was one of the main ports in the world from which cinnamon was exported. The arrival of the Portuguese marked a change in the history of the town. They made Galle their headquarters and destroyed many important monuments which were in the area.

The Dutch made renovations to the streets and added advancements such as storm water drains.oday much of the Dutch fort still stands, contradicting the ravages of time.
