Northern courtyard: On the east side facing the central fountain, this part has Bara Imam, a long corridor of rooms, and a pool that once housed the administrative wing and Shishe-Alat, meaning mirror image. Like the ornate stucco work that adorn the Khilwat Mubarak, it has Mughal domes and arches and many Persian elements. Built in Hyderabad at the time, these were characteristics of buildings. It is a building located opposite the Bara Imam that is its shisha or mirror image. For officials accompanying visiting dignitaries, the rooms were once used as guest rooms.
Khilwat Mubarak: The heart of Chowmahalla Palace is Khilwat Mubarak. By the people of Hyderabad, it is held in high esteem, as it was the seat of the Asaf Jahi dynasty.
Clock Tower: Affectionately called Khilwat Clock is the clock above the main gate to Chowmahalla Palace. For 251 years, it has been ticking away. Every week the mechanical clock is winded by an expert family of horologists.
Council Hall: A rare collection of manuscripts and priceless books are housed in this building. It is the place where the Nizam often met dignitaries and important officials. From the treasures of the Chowmahalla Palace Collection of the bygone era, today it is a venue for temporary exhibitions.
Roshan Bangla: The building was named after the Sixth Nizam, Mir Mahbub Ali Khan‘s mother Roshan Begum, and it is believed he to have lived here. It was decided to restore the Chowmahalla Palace and open it to the public in January 2005 by the present Nizam (Barkat Ali Khan Mukarram Jah) and his family. To document and restore the palaces of the first courtyard to its former glory, took over 5 years. Including the Rolls Royce, the palace also has a collection of vintage cars, which were used by the Nizam Kings.
