Tughlaqabad Fort
Six kilometres of sloping rubble wall around a city abandoned within a few years of being finished.
Ghiyas-ud-din Tughlaq built for defence and for nothing else. The walls batter inward at a steep angle, up to fifteen metres thick at the base, ringed by bastions and pierced by more than a dozen gates — architecture as a clenched fist, with none of the ornament that later Delhi forts wear. Inside were a citadel, a palace, and the grid of a planned city meant to hold a sultan's whole administration.
It lasted barely five years. Water was scarce, the succession was violent, and the capital moved on. Legend gives the credit to Nizamuddin Auliya, who was quarrelling with the sultan over labourers and is said to have cursed the city to stand empty or be inhabited by herdsmen — a prophecy that, for centuries, held. What is left is the most atmospheric ruin in Delhi: broken ramparts running over a rocky ridge, thorn scrub, peacocks, and almost no one. Across the road stands the sultan's own tomb, on a causeway that once crossed a lake.
- 01The rampartsA walkable circuit of massive sloped walls with long views over the southern ridge.
- 02Ghiyas-ud-din's tombA sloping-walled tomb of red sandstone and marble, reached by the old causeway.
- 03The underground chambersVaulted rooms beneath the citadel, cool even in May — carry a torch.
Wear real shoes; the ground is rough and unlit. Go with company and avoid the far ramparts late in the day.
