On two different hemispheres

Yesterday, Günter and I were in two different hemispheres. On this picture, he stands on the Western hemisphere whereas I'm in the Eastern hemisphere.

The picture was taken on the yard of the Royal Observatory in Greenwich, a World Heritage Site. We took the Thames Clipper from Houses of Parliament, got off the boat in Greenwich, then strolled through the Old Royal Naval College and climbed up the hill to where the Prime Meridian is marked with a metal strip in the floor and a sculpture.

We spent the evening with Thomas and Kathrin in one of Greenwich's many nice pubs and a Vietnamese restaurant, before returning to the Eastend with Docklands Light Railway and the tube.
