Howrah Bridge/ Calcutta

The former capital of British India, the port of Kolkata(formerly known as Calcutta) today forms the commercial and industrial hub of eastern india located on the eastern banks of the Hooghly River (about 150 kilometres upstream from the Bay of Bengal), which is a tributary of the Ganges. It is one of the four mega cities in India. During the British Raj Kolkata was known as the Jewel of the East and was the capital of the country till 1911. It still bears the Victorian imprint on its streets and structures. Today, it is still the most important city in the east.

As a first time visitor, Kolkata for me was indeed overwhelming,densely populated and polluted, ugly and desperate place, that to many, sums up the worst of India. Yet it's also one of the country's more fascinating centers producing some of India's finest literature, theater, films, art and culture. It is also known as the "City of Joy".
Kolkata has the Largest Railway Stations in the country with more than 50 Platforms.Howrah bridge is a landmark of that area. It connects the Howrah Railway station to Kolkata.This is a bridge that 80,000 vehicles and more than 1,000,000 pedestrians cross every day. I have never seen a bridge like this so crowded ever in my life.Just few minutes walk from the station you come across many Old British Buildings built in their times,standing strong as a rock even today.This biggest city markets of the east and a hub for wholesalers right next to the Railway Station.
I need to write a seperate travelogue, a brief about my experinces of how it was for me from the moment I reached kolkata untill i came back to Bangalore.Was a roller coaster ride. When I left Banglore I wanted to make a small trip to Darjelling and then Dhanbad( remember the movie Gangs of wassaepur)Because all these places are by few hours journey from Calcutta.
It is easy to be into shock when you first arrive in the city. If you look through the dirty exteriors of buildings, there is beautiful architecture. New Market is an eye opening experience for anyone only familiar with western life, especially the meat section (don't breath too deeply there, and never through your nose). If you give Kolkata a chance, it will steal a piece of your heart that will always remain there.
Returning back to the Kolkata diaries,There is much more to see than the dirty places in Kolkata
Esplanade is the heart of Kolkata. It consists of the region just north of the Maidan and includes Dalhousie Square with all its colonial British buildings.

Tollygunge is a locality of South Kolkata. It is flanked by the Eastern Railway south suburban line to the north, Lake Gardens and Golf Green in the east.
