@imperidox_: What do you think the purpose of this hole in the shutter is? 👀 At the Herschel Museum in Bath I came across a perfectly cut opening in the Georgian shutters. No one really knows why it’s there. Some believe it was part of an optical alignment tool William Herschel used while building his telescopes. Others think it may have been a tiny aperture to let in controlled light for polishing mirrors. Another theory is that it once held a piece of equipment that has long since disappeared. A small mystery hidden in plain sight that makes the history of this house even more fascinating. #historychannel #historyfacts #historylesson #historytok #historytiktok @Herschel Museum
