The rear of Media Centre included gardens designed by Christopher Bradley-Hole. A poem "Voices of White City" by Poet Laureate Andrew Motion was inlaid into the paving in the piazza. The site featured artworks such as Simon Patterson's art wall in Broadcast Centre which is based on First World War dazzle camouflage and Yuko Shiraishi's mural in Media Centre reception. She was also responsible for the overall colour scheme in both buildings. Energy Centre features the Olympic Rings as a marker of the finishing line of the 1908 Olympic marathon, with a plaque unveiled by IOC president Jacques Rogge in 2005.
