Royal Observatory and Prime Meridian

Today is pretty much summed up with one picture, and if you are familiar with this location you know exactly what we did today. :-)

Visiting the Royal Observatory was something that I always thought would be kind of cool, and a few weeks back I realized that it would be an easy day trip while in London. We took a boat up the Thames and got a fun introduction to several of the buildings that line it and after about an hour we got to Greenwich Pier. We grabbed some fish and chips in a pub and then walked up to the Royal Observatory.

It's no secret that I'm a pretty big geek, and visiting 0° longitude pretty much made the geek-o-meter peg into the red. I was more impressed with this arbitrary line in the dirt than I ever expected I would be. A huge bonus was the Time Gallery which had John Harrison's original time keepers on display — H1, H2, H3 and H4. I had read about these amazing time pieces in Dava Sobel's book Longitude a while back. It was amazing to see them first hand, still working.
