Now open: steampunk exhibition at the Royal Observatory
Steampunk artists have taken over the Royal Observatory! Let madcap inventors, stargazing scientists and elegant explorers take you on an adventure into a world where scientific convention and the laws of nature have been re-written. Their fabulous narrative lavishly reinterprets the science and drama of the 18th-century quest to find longitude at sea, inspired by the 300th anniversary of the Longitude Act. #LongitudePunkd

Explore this exclusive exhibition of eccentric inventions specially created by steampunk luminaries including award-winning novelist Robert Rankin – exuberantly blurring the boundaries between art and science, fact and fiction.
