By area Goa is the smallest state of India, located in West India known as Konkan. But Goa is the richest state of India and ranked as the best place and quality of life. Portuguese first arrived here in 16th century as merchants and took control soon thereafter. They ruled on Goa for around 450 years, and later annexed by India in 1961. Today, Goa is known for its beaches, world heritage architecture and churches- the place for worship.
