Purani Haveli the second Nizam of Hyderabad, Mir Nizam Ali Khan had taken over this from Rukunudhaulah of the Momin dynasty, in 1717. The main building is a symbol of 18th-century European architecture. His successor Sikander Jah lived here for some time and later shifted to Chowmahalla Palace. Due to this, these buildings are called Purani Haveli. In this building complex, Ayina Khaana (Mirror House) and Chini Khaana (Chinese Glass House) were constructed. The sixth and seventh Nizams were born at this palace, and did spend a part of their life at this palace.
