Flamsteed House at the Royal Observatory, a red-brick building with a red time ball on its turret, under a blue sky.

Official site

Royal Observatory Greenwich

The Royal Observatory stands on a hill in Greenwich Park; King Charles II commissioned it in 1675, and Flamsteed House, its first building, was completed in 1676 to a design by Christopher Wren. The Prime Meridian passes through the site, which gave its name to Greenwich Mean Time. It is now a museum of astronomy and timekeeping with a planetarium.
