In the 16th century, while the Mughals were building grand fortifications, mausoleums and mosques in north India, the Qutb Shahi dynasty also built majestic structures in their capital, present-day Hyderabad. Builders and patrons of learning, the Qutb Shahi dynasty ruled the region for 169 years in the 16th and 17th centuries. The complex includes forty mausoleums, twenty-three mosques, five baolis (step-wells), a hammam, pavilions and garden structures. The Aga Khan Trust for Culture (AKTC) is creating a heritage park, with conservation works carried out by master craftsmen, whose building skills have been passed from father to son for centuries.
