Forbidden City, Beijing, China
The Forbidden City is the imperial palace complex at the heart of Beijing, built between 1406 and 1420. It was the residence of 24 Ming and Qing emperors and the centre of Chinese political power until 1924; today it houses the Palace Museum and has been a UNESCO World Heritage Site since 1987. The photos, taken in 1994, 2002 and 2015, show its gates, courtyards and halls with yellow-tiled roofs.
