Located less than an hour outside of London, Greenwich’s Royal Naval College provided advanced training for officers between 1873 and 1998. The campus was designed by celebrated architect Sir Christopher Wren, and is situated on 271 acres along the Thames. In 1997, it was designated a UNESCO World Heritage Site, described as the “finest and most dramatically sited architectural and landscape ensemble in the British Isles.” Clive Gardiner contrasts the naval college’s vibrant, stately beauty with the darkened, smoke-filled city of London in the background, emphasizing that Greenwich offered a break from polluted city life that could easily be obtained by Tube. The tagline “at London’s service” was used on numerous posters at the time and denotes the democratic nature of the Tube, which was intended to provide city dwellers with affordable, accessible transportation to pleasant, rejuvenating destinations.
