The Citadel of Prayer: Khan-i-Jahan Junan Shah's 1375 Foundation
Standing like an austere medieval stone fortress in the heart of modern South Delhi, directly opposite the glittering contemporary shopping malls of Saket and Malviya Nagar, Khirki Mosque (Khirki Masjid) is one of the most architecturally unique, daring, and enigmatic Islamic monuments in the world. Built around 1375 CE during the reign of Sultan Feroz Shah Tughlaq, the mosque was commissioned by his brilliant prime minister (Wazir), Khan-i-Jahan Junan Shah, the son of the legendary Telangana convert Khan-i-Jahan Maqbool Tilangani.
Junan Shah was a visionary architectural patron credited with constructing seven monumental mosques across Delhi, but Khirki Mosque represents his absolute structural masterpiece. Situated within the historic confines of Jahanpanah—the sprawling fourth city of Delhi founded by Muhammad bin Tughlaq in 1327 to enclose the gap between Qila Rai Pithora and Siri—the mosque was designed as both a grand congregational house of prayer and a fortified defensive sanctuary capable of protecting neighborhood residents during urban sieges.
The popular name 'Khirki' derives from the Hindi and Urdu word for window (*khirki*). While traditional congregational mosques throughout the Islamic world feature vast open-air courtyards surrounded by arched cloisters, Khirki Mosque was constructed on a revolutionary 'covered' plan, punctuated by intricately pierced stone lattice windows (*jalis*) on its upper exterior walls that flood the interior vaulted corridors with dappled, geometric light.
Free Public Entry & Atmospheric Natural Lighting
Khirki Mosque is managed by the Archaeological Survey of India (ASI) with free public entry daily from sunrise to sunset. The interior of the mosque is famed among architectural photographers for the dramatic geometric patterns created by morning and late afternoon sunlight streaming through the pierced stone lattice windows (khirkis) into the dim vaulted colonnades.
Architectural Geometry: The Covered Cruciform & 89 Vaulted Domes
The plan of Khirki Mosque is a triumph of mathematical symmetry and geometric daring. Built upon a massive raised stone basement containing twenty-eight vaulted storage cells, the mosque forms a perfect square measuring fifty-two meters on each side. The exterior walls, constructed of local grey quartzite rubble masonry coated with plaster, feature the characteristic Tughlaq inward slope, anchored at each of the four corners by colossal tapering cylindrical bastion towers that resemble medieval castle turrets.
Internally, the mosque completely subverts orthodox Islamic architectural conventions. Instead of a single vast central courtyard, the interior is divided into a symmetrical grid of twenty-five equal squares. Four of these squares are left unroofed as small, open-air inner courtyards that channel natural daylight and fresh air into the core of the building.
The remaining twenty-one squares are fully roofed by a breathtaking forest of eighty-nine small hemispherical stone domes arranged in clusters of nine, supported by heavy square stone piers and multi-tiered arches. This covered cruciform layout—rarely seen outside fourteenth-century Anatolia—protected worshippers from the blistering summer sun, winter winds, and torrential monsoon downpours of northern India.
The Windows of Light: Pierced Lattice Jalis & Shaded Corridors
The defining aesthetic glory of Khirki Mosque is its sophisticated manipulation of interior light and shadow. The upper tiers of the north, south, and east exterior walls are pierced by projecting bracketed balconies (*jharokhas*) fitted with thick red sandstone and quartzite lattice screens (*jalis*) carved with geometric star, diamond, and hexagonal motifs.
As the sun traverses the Delhi sky from dawn to dusk, shafts of intense golden sunlight pierce through these stone lattices, projecting sharp geometric patterns across the cool stone floors, fluted pillars, and vaulted domes. Walking through the shadowy, labyrinthine colonnades feels like stepping into a subterranean stone forest or an ancient European Romanesque crypt.
The western Qibla wall is punctuated by an austere, deeply recessed stone *mihrab* (prayer niche) flanked by carved calligraphy panels, while the central prayer axis aligns with the open light wells to create an intensely meditative, monastic atmosphere of spiritual seclusion.
Narrow Village Alley Access & Dim Interior Footing
The mosque is located within the dense urban fabric of Khirki Village, directly opposite Select Citywalk Mall. Approach roads through the village are narrow and congested with two-wheelers; arrive on foot from Press Enclave Marg. The interior vaulted chambers are dimly lit; watch your footing over historic stone plinths and uneven floor pavers.
The Fortress Sanctuary: Basement Cells & Battered Bastions
Beyond its sacred religious function, Khirki Mosque was designed with unambiguous military and defensive capabilities. The massive raised plinth upon which the mosque rests elevated the prayer floor nearly three meters above the surrounding village ground level, making the complex impervious to casual street assault.
The basement substructure contains twenty-eight barrel-vaulted stone chambers opening to the exterior, which historically served as secure storage vaults for municipal grain reserves, water cisterns, and temporary merchant stalls (*sarai* accommodations) for traveling caravans. The three monumental entrance gateways—on the north, south, and east—are reached via steep flights of stone stairs and feature fortified double-gate portals flanked by tapering defensive bastions equipped with arrow slits.
In times of internal rebellion or frontier invasions, neighborhood families could retreat inside the massive stone fortress, seal the heavy wooden doors, and withstand prolonged skirmishes while continuing their daily prayers in safety beneath the vaulted domes.
The Medieval Anomaly: Khirki Village vs. Select Citywalk
Today, Khirki Mosque presents one of the most surreal and thought-provoking urban juxtapositions in modern Delhi. Situated within the dense, bustling urban village of Khirki—filled with narrow pedestrian alleys, local tea stalls, Afghan bakeries, and immigrant artist workshops—the 650-year-old stone fortress stands directly across the street from the neon-lit glass facades, luxury brand boutiques, and multiplex cinemas of Select Citywalk Mall.
Extensive structural conservation carried out by the Archaeological Survey of India (ASI) has stabilized the eighty-nine domes, cleaned decades of accumulated soot, and restored collapsed stone lintels while maintaining the monument's quiet, dignified public access.
Stepping out of the air-conditioned consumerist bustle of the 21st-century mall and crossing the street into the cool, silent, 14th-century vaulted stone chambers of Khirki Mosque is a transcendent time-travel experience, underscoring Delhi's incomparable capacity to preserve ancient sacred architecture within the vibrant chaos of the modern metropolis.
