Galle Fort is in Galle, which is located at the extreme southwest corner of the island, in the southwest coast of Sri Lanka, where the shoreline turns east towards Matara and Tangalle. The fort, like most of the forts in Sri Lanka, is built on a small rocky peninsula, belonging to the sea as much as to the land. As it exists today, it covers an area of 52 hectares (130 acres).
Highway A2 provides road links to Galle from Colombo (a distance of 113 kilometers (70 mi)) and the rest of the country along the west coast or from the east along the south coast. Since 2012 an expressway has linked Galle to Colombo. Rail links are also available to Colombo and Matara. Sea route is through the Galle Port at the Galle Harbor.
