Lewis Demisemiseptcentennial

Uig Chessman 2006 (4:53) • 'The Lewis (Uig) Chessmen, a set of 12th century chess pieces carved from walrus tusk, were found on Uig Sands in 1831. The video shows a carved wooden chessman being placed, close to where the originals were found, to commemorate the event.'

Or Quartoseptcentennial? Or Terquasquicentennial? Or Septaquintaquinquecentennial? Whatever you call it, I like the video!
