Old Meridian Line

The tree needs pruning, because all you can see through this slot is the tree.

We all think of Greenwich in east London as being home to the Prime Meridian — longitude line 0°, separating east from west. It was only in 1884 that the longitude line running through the observatory at Greenwich was internationally recognised as the Prime, however. This line in Richmond, west London, is just one of the others.
