This is the top of the building. What you see on the left is the well understood (previously not understood by me) image of a Greek sailing ship (I thought it was a peacock…). The British Lion used to occupy the other half but in 1864 when the British left they took their Lion with them.
Which reminds me, whenever art or artifacts come up in casual conversation, I am reminded by my new Greek friend how very very much they do not like the British because they stole stole I tell you everything they could get their hands on. “What if we marched over there and just took Big Ben?!” they say.
