Purani Haveli is one of the rarely historical palaces in Hyderabad. It was also known as Haveli Khadeem, which means old mansion. It’s also known by its other name as Haveli Khadeem and it was the official residence of the Nizam. It is built during the mid- during the Qutub Shahi dynasty in the late 16th century.

Ali Khan Bahadur constructed this mansion for his son Sikander Jah. It was constructed in a lovely mix style of European and Indian architecture. Sikander Jha lived here for some time and later shifted to Khilwat Mahal. Due to this, these buildings are called Purani Haveli. In this building complex, Ayina Khaana (Mirror House) and Chini Khaana (ChineseGlass House) were constructed.

The Haveli is U in shape with a single storied central building, bordered by two oblong wings running parallel to each other and the residential palace located perpendicularly in the middle. The main building resembles 18th-century European palaces. A unique feature of this palace is the world's longest wardrobe, built in two levels with a hand-cranked wooden lift(elevator) in place. This occupies the entire length of one wing of the palace. The courtyard, however, is definitely Indian, forming a comfortable combination of aesthetics between the two.

Purani Haveli also houses the Nizam’s museum exhibiting the vast collection of artifacts of the last Nizam of the state of Hyderabad. It includes souvenirs, gifts, and mementos and also vintage cars on display including a 1930 Rolls-Royce, a Packard, and a Jaguar Mark.

Purani Haveli is rare sight to visit now but still one who has love towards ancient historical monuments can visit this place which is open on all days except Friday with a free entry.
