Al-Khimyah explores the work of the Aga Khan Trust for Culture (AKTC) in the historic city of Cairo, Egypt. The film shines a spotlight on the 30-hectare Al-Azhar Park - converted from a mound of rubble - and the stories of local residents of the adjacent al-Darb al-Ahmar neighbourhood. The park has also proven to be a powerful catalyst for urban renewal, evolving beyond the green space itself to include the restoration of monuments and public spaces, and socioeconomic initiatives including housing rehabilitation, microfinance, crafts apprenticeships, and healthcare. Since opening in 2005 after 20 years of careful excavation and design, Al-Azhar Park has provided much-needed leisure and recreational space to the inhabitants of the city, and is today often referred to as "Cairo's green lung."
