Kolkata or Calcutta is a 350-year-old metropolis which is not only the capital of the Indian state of West Bengal but was also the erstwhile capital city of India. Kolkata is located on the bank of the Hooghly River, and the city is undoubtedly the principal cultural, educational and commercial center of East India. The Port of Kolkata on the Hooghly River is the oldest operating river port in India. The British East India Company had primarily developed the city after a long era of the Nawabi Rule. The native Bengali inhabitants of the city consider Kolkata to be India?s intellectual, artistic and cultural capital. Often called the "City of Joy," this friendly city and its friendlier people are extremely passionate about their culture and heritage, Tagore, politics and literature. Kolkata experiences a hot and sultry summer and a moderately cold winter. The city celebrates almost every Indian festival and gets especially decked up in autumn during the Durga Puja. A typical street in Kolkata consists of distinctively close-knit neighborhoods, freestyle intellectual exchanges, old yellow ambassador taxis, street food joints and sweet shops. North Kolkata hosts the older neighborhoods with huge old-fashioned houses and narrow streets, whereas South Kolkata is home to the posh and upscale Bengalis. Central Kolkata has the central business district; East Kolkata is the new and upcoming area of the city that is randomly developing.
