The Crystal Palace, the great glass building that had defined this hilltop since 1854, burned spectacularly in 1936. The Marine Aquarium on the same site collapsed in 1941 during the demolition of the Palace's blackened north water tower. By the mid-1950s the hilltop was a wasteland of Victorian masonry and waist-high weeds, until contractors arrived with two derricks (one 230 feet tall, one 125 feet) and a winch, and started building. By the time they finished, the new transmitter mast stood 219 metres above Sydenham Hill, which itself sits 109 metres above sea level. That made it the highest structure above sea level anywhere in London. It still is.
