Found this description: Circumsphere in the Thames Circumsphere - Chris Marshall & Stephen Lewis. This globe like structure was constructed from more than a mile of galvanised steel rod. It supports a number of steel disks, that show the route of Sir Francis Drake's circum-navigational voyage around the earth. The voyage was completed at this waterfront in 1581. Circumsphere is mounted on a Dolphin; the name given to many small mooring structures that sit out in the river Thames, that provided low-tide moorings for ships, barges, tugs and lighters.
