Chepauk palace in Madras

What once was the Chepauk palace in Madras. 

Of the Nawab of Carnatic. Photograph taken around 1851 by Frederick Fiebig in c.1851. This is a distant view of the portion known as  Humayan Mahal; the other part of the palace was the  Khalsa Mahal. The designer was probably Paul Benfield, an engineer of the British East India Company. The Nawabs remained in residence until the dynasty died out in 1855 and the palace was acquired by the government. Khalsa Mahal was subsequently incorporated into the Public Works building and Engineering College, and Humayan Mahal was integrated into the Revenue Board building, completed in 1871.
