We invite you to the premiere of "Potential Energy," a brand-new documentary revealing the incredible story of one of the world’s oldest surviving Crossley four-stroke engines — hidden under the attic of the old Police Station for over a century.
During renovations in the attic of CoDE The Court - the building above The Lost Close - an exceptionally rare Victorian Crossley engine was found. Built in 1878, this marvel of Victorian engineering, it was far ahead of its time, used to regulate the temperature of the Edinburgh Police Chambers, and its survival offers a rare glimpse into 19th century innovation. This rare piece of engineering history is believed to be the second oldest surviving engines of its kind in the world, produced by the pioneering Manchester firm that once powered the industrial revolution.
Through the documentary and a Q&A session, you'll hear the full story of how the engine was found, preserved, and moved from the attic to the underground vault. Following the Q&A, you will get the opportunity to see the Crossley Engine in person and visit The Lost Close, an underground hidden-gem.
