When we hear about things being built to last, we usually think in terms of years or decades ... or maybe, centuries. But millennia? Well yes, if you’re talking about the 10,000 Year Clock. As its name implies, the 200 foot (61 meter)-tall timepiece is intended to run for 10,000 years, in a remote cave in West Texas. The clock’s “century hand” will advance one space every 100 years, although individuals who make the trek to the cave will be able to hear it chime once a day. The whole project is designed to get people thinking in the long term.
