Lying east of Qutab Minar the third city of Delhi with 13 gateways is Tughlaqabad built by Ghiyas-ud-din Tuglaq. In the southern periphery of Delhi are the ruins of a massive fort, once the capital of the Tughlaq kings. It was an impregnable fortification built by Sultan Ghiyasuddin Tughlaq in 1321. The Elegant tomb of the emperor in red sandstone with its sloping walls and white dome, located near the fort, is considered to be one of the best examples of Tughlaq architecture.

The massive Tughlaqabad Fort, is not only symbolic of the might of the Tughlaq dynasty, but it is a piece of architectural marvel. It was a part of the dream project of Ghiyas-ud-din Tughlaq when he built the capital at Tughlaqabad. However, this powerful edifice did not last long and fell to the curse of a saint. The crumbling ruins of the Tughlaqabad Fort convey a sense of lost grandeur. The massive ramparts, battlements, and the mammoth stonework of this fort speak highly of the engineering skills of the workers who constructed it. The fort served the dual purpose of a defensive structure as well as the imperial capital of Ghiyas-ud-din Tughlaq. There are a number of monuments within the precincts of this fort.

Tughluqabad Fort was situated on high rocky ground, an ideal location to withstand enemy attacks. The origin of the historic city of Tughlaqabad and the Tughlaqabad Fort goes to the period of the Delhi Sultanate. The Tughlaqs who followed the Khiljis were great builders and the city of Tughlaqabad and Tughlaqabad Fort were their first major architectural achievement. The story behind Ghazi Malik (founder of the Tughlaq dynasty) was once a slave of Mubarak Khilji, the last Khilji sultan. One day, while walking by the area Ghazi Malik suggested to his master that the rocky prominence would be an ideal site for building a fort. The Khilji sultan laughed at his slave and suggested that the slave build a fort there when he became a sultan. When Ghazi Malik, as Ghiyas-ud-din Tughlaq, founded the Tughlaq Dynasty in 1321, he did just that—Tughlaqabad is Delhi’s most colossal and awesome fort, even in its ruined state. In fact Ghiyasuddin had selected this site for the fort when he was a mere soldier. The fort of Tughlaqabad was completed rapidly in a short span of four years. Within its sky-touching walls, double-storied bastions, and gigantic towers were housed grand palaces, splendid mosques, and audience halls. Tughlaqabad is a formidable reminder of Delhi’s embattled past and the terror. It was a period of political unrest and the Delhi Sultanate had to face a number of attacks from hoards of marauding Mongols, who descended on it in waves from the north. The massive fortifications of Tughlaqabad, with immense circular bastions, were raised by Ghiyas-ud-din to protect his subjects.

There are a number of legends associated with Tughlaqabad. It is often said that the skulls of the killed Mongol marauders were used in the construction material of this awesome fort. Its construction involved a legendary quarrel with the saint Nizam-ud-din. When the Tughluq ruler took the workers whom Nizam-ud-din wanted for work on his shrine the saint cursed the king with the warning that only the Gujjars (shepherds) would inhabit his city. The demise of Tughlaqabad was not brought about by any foreign invasion, but to the curse of a Sufi Saint Nizam-ud-din. The legendary quarrel between the two started when Ghiyas-ud-din Tughlaq did not allow his people to work for the saint on the construction of a baoli (step well), which angered the saint. A protracted tiff followed, which offended the saint and led to his famous prophecy “Hunuz Dilli dur ast” (Delhi is yet far away), for the sultan was then out in Bengal. His prophecies proved true. Ghiyas-ud-din was killed at a place near Delhi when a shamiana (canopy) collapsed over him during a reception arranged by his son. The sultan could not reach Delhi alive. His successor chose to build his own fort and deserted Tughlaqabad. It is generally believed that the death of Ghiyas-ud-din Tughlaq was engineered and plotted by his son. One story describes that Muhammad bin Tughlaq killed his father by building a false wooden balcony, which collapsed and killed Ghiyas-ud-din. The son murdered and ascended the throne of Delhi, thus making the prophecies of Saint Nizam-ud-din come true. The massive block walls glow a beautiful golden colour in the afternoon sun. The remains of underground markets and some royal residences are visible inside the walls.

Tughlaqabad is the third city of Delhi, located about 10 kms. east of Qutub complex along the Mahrauli-Badarpur Road.
