Sultanpur Lodhi was also mentioned as important place in famous "Ain-e-Akbari". The city in those times had many Royal Gardens and farms. At present, relics of these royal buildings built at that time, are still present. One of these is "Hadera". It was once a marvelous building used as place of rest for the royal family on their way to royal gardens. It was also used as place of entertainment for royal family and to organize dances and other royal functions. This place is now just an old & neglected building.
