Renowned for its beaches, places of worship and world heritage architecture, Goa is visited by large numbers of international and domestic tourists each year. It also has rich flora and fauna, owing to its location on the Western Ghats range, which is classified as a biodiversity hotspot.
In 1510, the Portuguese defeated the ruling Bijapur sultan Yousuf Adil Shah with the help of a local ally, Timayya. They set up a permanent settlement in Velha Goa (or Old Goa). This was the beginning of Portuguese rule in Goa that would last for four and a half centuries, until 1961.
