[citation needed] The Sixth Nizam, Mir Mahbub Ali Khan, is believed to have lived here and the building was named after his mother Roshan Begum.

The former Nizam (Barkat Ali Khan Mukarram Jah) and his family decided to restore the Chowmahalla Palace and open it to the public in January 2005.

[2] The displays in the museum depict the origin and evolution of Hyderabad, achievements and valuable contribution of the Nizams towards the development of the state, and the social lifestyle of the royal family.

The vision for the restoration project was to rescue the exemplary palatial complex and to establish a contemporary civic use as a museum showcasing the splendour and valour of the erstwhile Nizams.

In the second stage, structures that were in danger of collapsing had to be stabilised, and other urgent repairs like waterproofing and propping had to be made to prevent further damage.

[15] In order to preserve the integrity of these ancient structures, their conservation was carried out using traditional craftsmen and techniques, and several building components were saved from demolition.

Many architectural features, including granite arches, elaborate lime plaster work, and terracotta balusters, were restored carefully in their original design in addition to structural repairs and stabilisation.

[15] Apart from bringing back the past glory of the palace complex and reviving traditional materials and craftsmanship, the project also created a cultural oasis in the heart of the city.
