Galle is a city situated on the south-western tip of Sri Lanka, 119 km from Colombo. Galle was known as Gimhathiththa (although Ibn Batuta in the 14th century refers to it as Qali) before the arrival of the Portuguese in the 16th century, when it was the main port on the island. Galle reached the height of its development in the 18th century, during the Dutch colonial period. Galle is the best example of a fortified city built by Europeans in south and southeast Asia, showing the interaction between European architectural styles and south Asian traditions. The Galle fort is a world heritage site and the largest remaining fortress in Asia built by European occupiers. Other prominent landmarks in Galle include St. Mary's Cathedral founded by Jesuit priests, one of the main Shiva temples on the island, and the Amangalla, a historic luxury hotel. Galle is the main town in the most southerly part of the island, with a population of around 100,000, and is connected by rail to Colombo and Matara. It is home to a cricket ground, the Galle International Stadium. Rumassala kanda in Unawatuna is a large mound-like hill, which forms the eastern protective barrier to the Galle harbour. Local tradition associates this hill with some events of the Ramayana.
