The Companion Citadel: Muhammad bin Tughlaq's Imperial Foundation
Perched atop an isolated rocky promontory of the Aravalli range roughly eight hundred meters southeast of Tughlaqabad, Adilabad Fort stands as one of Delhi's most atmospheric, forgotten, and underappreciated Sultanate ruins. Built around 1326–1327 CE by Sultan Muhammad bin Tughlaq—the brilliant, controversial son and successor of Ghiyas-ud-din Tughlaq—the fortress was originally christened Muhammadabad before becoming known historically as Adilabad (the Abode of the Just).
Muhammad bin Tughlaq constructed Adilabad as an intimate, heavily fortified royal retreat and companion fortress to his father's colossal city. Recognizing that Tughlaqabad's sheer size (six kilometers of perimeter) made it difficult to garrison efficiently against surprise cavalry raids, the young Sultan erected this compact, muscular stronghold on an adjacent ridge overlooking the artificial reservoir that separated the two hills.
Though smaller in scale than Tughlaqabad, Adilabad was engineered with superior defensive sophistication. It functioned as an impenetrable citadel where the Sultan could conduct sensitive administrative affairs, house his elite royal guards, and maintain his personal treasury before his fateful decision in 1327 CE to construct the vast walled city of Jahanpanah and transfer the imperial capital to Daulatabad.
Free Public Access & Connecting Trail to Tughlaqabad
Unlike the ticketed Tughlaqabad Fort, Adilabad Fort is maintained by the Archaeological Survey of India (ASI) with completely free public admission. The fortress is situated approximately 800 meters southeast of Ghiyasuddin Tughlaq's tomb across an unpaved walking track. Visiting both fortresses together provides an exceptional comparative overview of early Tughlaq military architecture.
Concentric Fortifications: The Outer Bailey & Royal Ward
Adilabad Fort is designed on a sophisticated concentric plan comprising two distinct defensive circuits: an extensive lower outer bailey and a heavily fortified upper citadel (the inner ward). Assembled from rough-hewn quartzite blocks quarried directly from the hill, the walls are built with the characteristic Tughlaq inward slope (batter) and bonded with thick lime-surkhi mortar.
The outer bailey, measuring roughly one thousand meters in circumference, was reinforced by nineteen projecting semicircular bastions. Two monumental gateways gave access to the lower enclosure—one on the southeast facing the ancient trade road to Badarpur, and a grander northern gateway facing Tughlaqabad across the historic lake bed.
The northern gateway is a masterpiece of defensive engineering. Approached via a steep, switchback ramp that exposed assaulting cavalry to crossfire from flanking bastions, the gate was secured by double sets of heavy wooden doors and featured overhead machicolations from which defenders could pour boiling liquids onto besiegers trapped in the entrance passage.
The Palace of a Thousand Pillars: Architectural Remains
Ascending from the outer bailey through an internal fortified gateway brings visitors into the high inner citadel. At the summit of the hill stood the Sultan's private palace, which medieval chronicler Ziauddin Barani and Moroccan traveler Ibn Battuta identified as an early iteration of the Qasr-i-Hazar Sutun (Palace of a Thousand Pillars).
Ibn Battuta, who served as a royal judge (qazi) under Muhammad bin Tughlaq in the 1330s, left a vivid eyewitness description of the Sultan's court: an immense hall supported by carved wooden pillars with exquisitely painted and gilded ceilings, where the monarch received foreign ambassadors, distributed lavish gifts of horses and silk robes, and dispensed justice with mercurial intensity.
While the wooden superstructures perished centuries ago, archaeological excavations conducted by the ASI revealed massive stone column bases, sunken storage vaults, deep water cisterns, and a subterranean escape tunnel cut directly through the living rock toward the southern valley, confirming the monumental scale of the fourteenth-century royal residence.
Remote Forested Ridge, Isolated Paths & Sturdy Footwear Required
Adilabad Fort is largely unfrequented by mass tourism and lacks commercial facilities or on-site drink vendors. Visitors should explore in small groups during daylight morning hours. The rocky hill trail features thorny acacia bushes and loose quartzite scree; wear thick-soled walking shoes and bring your own drinking water.
Satellite Bastions: Nai Ka Kot & The Tughlaq Defense Matrix
Directly south of Adilabad, across a narrow ravine, sits another enigmatic ruin known as Nai Ka Kot (the Barber's Fort). Local folklore attributes this miniature stone fortress to the royal barber of the Tughlaqs, though historians confirm it was an advanced military outpost and cavalry watchtower guarding the southern approach to Adilabad.
Together, Tughlaqabad Fort, the Tomb of Ghiyasuddin, Adilabad, and Nai Ka Kot formed a unified, interlinked military defense matrix spanning three contiguous hills. The artificial lake impounded between the ridges acted as a natural moat, while elevated stone causeways and subterranean couriers allowed rapid troop repositioning between the strongholds during attacks.
This formidable network of fortifications demonstrated the advanced military preparedness of the early Tughlaqs, who transformed the wild southern crags of Delhi into an impenetrable frontline fortress capable of repelling the most ferocious Central Asian cavalry invasions of the fourteenth century.
The Unspoiled Ridge: Panoramic Views & Timeless Solitude
Today, Adilabad Fort offers one of the rarest historical experiences in the National Capital Territory: complete, undisturbed peace amidst monumental medieval ruins. Because the site remains off the mainstream tourist circuit, visitors often have the entire hilltop fortress entirely to themselves.
Standing upon the high eastern ramparts at sunrise, one commands a magnificent 360-degree panorama of Delhi's southern landscapes. To the northwest, the massive battlements of Tughlaqabad and the white marble dome of Ghiyasuddin's tomb rise proudly above the morning mist. To the east and south, the rolling green scrublands of the Asola Bhatti Wildlife Sanctuary stretch toward the horizon.
The only sounds breaking the silence are the calls of wild peacocks, the rustle of wind through acacia leaves, and the gentle cooing of doves nesting in the ancient arrow slits. For discerning heritage travelers, exploring Adilabad Fort is an evocative journey into the raw, unvarnished stone heart of medieval Delhi.
