Amid a tangle of alleys, attracting hoards of devotees, is the vibrant marble shrine of the Muslim Sufi saint, Nizam-ud-din Chishti. He died in 1325, aged 92, but the mausoleum has been revamped several times, and dates from 1562. Other tombs include the later grave of Jahanara (daughter of Shah Jahan), and the renowned Urdu poet, Amir Khusru. It’s one of Delhi’s most atmospheric pleasures to hear Sufis sing qawwali, at around sunset after evening prayers, on Thursdays and feast days.
