On 4 May, Imran Khan, Prime Minister of the Islamic Republic of Pakistan, inaugurated the restoration of the 400-year-old "Picture Wall" of Lahore Fort in Pakistan. The Picture Wall is one of the principal features of the Lahore Fort UNESCO World Heritage Site. The conservation of the 240-foot-long western facade has reportedly been carried out by the Aga Khan Trust for Culture (AKTC), and its country affiliate, the Aga Khan Cultural Service-Pakistan (AKCS-P), in collaboration with the Walled City of Lahore Authority (WCLA). Built approximately 400 years ago during the Mughal era, it is one of the largest murals in the world. Salman Beg, CEO of AKCS-P said: "The process of conservation included the stabilisation and consolidation of the Picture Wall’s structure, as well as its decorative elements, and warranted the expertise of both heritage crafts as well as conservators. It also included archaeological excavation in order to expose the original Mughal era floor level."
