Greenwich, England

The two domes are part of the Royal Navy College. It was designed by Christopher Wren. Up and to the right, out of sight of this photo is the Royal Observatory of Greenwich. Home of the Prime Meridian and Time. (GMT or UTM)

Tonight we walked past the observatory to see the green laser that is broadcast along the Prime Meridian from the top of the observatory. Quite a sight. Eastern and Western hemispheres at our feet
