According to historians, the prison cell, popularly known as 'Garbha Griha' ( Sanctum Sanitorium ) , in the temple premise is the exact place where lord Krishna was born. The stone walled cell is reminiscent of the cruelty of King Kansa. Many statues and sculptures of the bygone era were found on excavating the site. The prison cell was gradually turned into the present beautiful temple. Lakhs of devotees throng the temple during Janmashtami. The festivities and celebrations during the festival is famous all over India. Celebrations begin during mid night with the birth of Lord Krishna.
The clearance of the birthplace of Lord Shri Krishna, led to the recovery of many portions of a 1500 year old temple, including the sanctum sanctorum (Garbha Griha) and a throne. The Medhi and sanctum sanctorum have been preserved. It is, indeed, the blessings of the Lord that when Emperor Aurangzeb demolished the temple and erected the Idgah on its plinth, the Idgahwas actually constructed on the Sabha Mandap (prayer-hall) of the temple; the sanctum sanctorum, miraculously, remained intact and got buried under the debris. Resurrection of such an auspicious place has ensured that the devotees, once again, can enjoy the blessings of the Lord at His birthplace.
