Although the modern city of Bhubaneswar was formally established in 1948, the history of the areas in and around the present-day city can be traced to the 7th century BCE and earlier. It is a confluence of Hindu, Buddhist and Jain heritage and includes several Kalingan temples. With many 6th-13th century CE Hindu temples, which span the entire spectrum of Kalinga architecture, Bhubaneswar is often referred to as a "Temple City of India". With Puri and Konark it forms the 'Swarna Tribhuja' ("Golden Triangle"), one of eastern India's most visited destinations.
