Historical Background of the Stadium: The Eden Gardens is the oldest cricket ground in India, considered as one of the finest in the world. The history of the Indian Cricket is irrevocably bound up with that of Calcutta Cricket Club, which did the pioneering p ioneering work in cricket in the whole of the eastern region of India. The present Eden Gardens Cricket Club came in existence some time in the year 1864. It is not certain as to whom the land belonged be longed to although some records show that it was the property of then Maharaja of CoochCooch Behar while some other records state that it belonged to the Auckland Family. However, the fact remains that the land was effectively passed into the hand of the Governor General's family who in turn presented it to the citizens of Calcutta for recreation. In course of time Calcutta Cricket Club established with its headquarters h eadquarters at the Eden Gardens. The pavilion was built in 1871 and cricket was played for a long period in Sylvan surroundings.

The first ever first-class match, played here was in 1917-18, while the first Test match was against Douglas Jardine's MCC in January 1934. Since then the ground has hosted many many Tests matches. In February 1987, the stadium hosted its first ODI match - against Pakistan.  As a part of modernization of the stadium during the 1987 World Cup, where the final match was held, covered stands were built all around, with a modern Club House and pavilion. Then, in November 1993, four gigantic flood lights installed when a five-nation tournament was played to celebrate the CAB Diamond Jubilee, where day-night one-day international matches were played at this ground. It can now also legitimately boast of having one of the largest accommodation (nearly 120, 000) in the world for viewing the game.
