While Lahore Fort is celebrated for its grand architectural marvels, such as the Sheesh Mahal and the Diwan-i-Khas, far less is known about the mysteries hidden beneath the surface. Conservation efforts have traditionally focused on the striking monuments above the ground. The subterranean chambers and basements that support them have often been overlooked. The historic chambers were inaugurated recently to mark the completion of a major phase of their conservation, a collaborative effort by local and international entities. The intervention was an integral component of the Heritage and Urban Regeneration: Tourism Development in Lahore Fort and its Buffer Zone (HURL) project led by Aga Khan Cultural Service-Pakistan (AKCS-P) in partnership with the Walled City of Lahore Authority.
