Très intéressant
Au sommet de l'Observatoire, on observe un curieux ballon rouge surmonté d'une croix qui monte tous les jours à 13h qui permet aux marins de savoir l'heure.
Le site offre un panorama magnifique sur les Docklands.
On peut même franchir de chaque côté le célèbre méridien de Greenwich représenté sur le sol par un tracé lumineux.
