Bhubaneswar, also spelled Bhubaneshwar, is the capital of the Indian state of Orissa, officially spelled Odisha. The city has a history of over 3000 years starting with the Mahamegha-bahana Chedi dynasty (around 2nd century BCE) who had Sisupalgarh near present-day Bhubaneswar as their capital. Bhubaneswar has been known by names such as Toshali, Kalinga Nagari, Nagar Kalinga, Ekamra Kanan, Ekamra Kshetra and Mandira Malini Nagari (City of Temples) otherwise known as the Temple City of India. It is the largest city of Orissa, and a center of economic and religious importance in the region today.
Bhubaneswar's possession of magnificent sculptures and architectural heritage, coupled with the sanctity as Ekamrakshetra make this one of the great religious centres of Orissa since early medieval days. With its large number of Hindu temples (over 600 in number), which span the entire spectrum of Kalinga architecture, Bhubaneswar is often referred to as a Temple City of India and together with Puri and Konark it forms the Swarna Tribhuja (Golden Triangle); one of the most visited destinations in eastern part of India.

Like Jamshedpur, Chandigarh, it is one of the first planned cities of modern India With the Chandaka forest reserve on the fringes, the city with an abundance of greenery, is one of the cleanest and greenest cities of India.
