One of the earliest Mughal tombs in existence lies in the middle of an unsuspecting roundabout in Nizammudin.

A few decades ago, Sabz Burj was converted into a Police station, and the painted interior was plastered over.

The plaster was only removed a few years ago, when conservationists from the Nizamuddin Renewal uncovered what might be the earliest surviving painted ceiling anywhere in Delhi.

Ebba Koch’s fascinating new research has shown that it may, in fact, be the tomb of Maham Begum, the Empress of India and mother of Emperor Humayun.
