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 the Temple City of India. The modern city of Bhubaneswar was designed by the German architect Otto Königsberger in 1946. Like Jamshedpur and Chandigarh, it is one of the first planned cities of modern India. With the Chandaka reserve forest on the fringes, the city, with an abundance of in-city greenery and an efficient civic body, has become one of the cleanest and greenest cities of India. The State Museum of Bhubaneswar offers an extensive selection of archaeological artifacts, weapons, local arts and crafts as well as insights into Odisha's natural and tribal history.
