In this photograph taken on August 6, 2024, a worker mops rain water at Rajkumari Ratnavati Girls' School, in Kanoi village near Jaisalmer, in India's desert state of Rajasthan. In the sweltering heat of India's Thar desert, where summer highs soar above 50 degrees Celsius, an architecturally striking school is an oasis of cool thanks to a combination of age-old techniques and modern design. The Rajkumari Ratnavati girls' school uses the same yellow sandstone as the 12th-century fort in nearby Jaisalmer, in India's western state of Rajasthan, dubbed the "golden city" due to the colour of the rock.
