Bhubaneswar, also spelt as Bhubaneshwar, is the capital of the Indian state of Odisha. It is the largest city in Odisha and is a centre of economic and religious importance in Eastern India. Along with the old town, the region of Bhubaneswar, historically was often depicted as Ekamra Kshetra. With the diverse ranges of heritage resources, it showcases significant sacred cultural landscape components which have evolved with the support of available natural resource base and cultural trigger. Although the modern city of Bhubaneswar was formally established only in 1948, the history of the areas in and around the present-day city can be traced to 1st century BCE and earlier. With many 8th-12th 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, one of eastern Indias most visited destinations. Bhubaneswar replaced Cuttack as the capital on 19 August 1949, 2 years after India gained its independence from Britain. The modern city was designed by the German architect Otto Königsberger in 1946. Along with Jamshedpur and Chandigarh, it was one of modern Indias first planned cities. Bhubaneswar and Cuttack are often referred to as the twin cities of Odisha. The metropolitan area formed by the two cities had a population of 1.7 million in 2011. Bhubaneswar is categorised as a Tier-2 city. An emerging information technology and education hub, Bhubaneswar is one of the countrys fastest-developing cities.
