Good morning Rusty!
It is 12.15am!
Right...... a much delayed (sorry about that!) history lesson!
The Royal Observatory came into being through Charles II.
The site was chosen by Sir Christopher Wren
The king also created the position of Astronomer Royal, to serve as the director of the observatory and to "apply himself with the most exact care and diligence to the rectifying of the tables of the motions of the heavens, and the places of the fixed stars, so as to find out the so much desired longitude of places for the perfecting of the art of navigation."
It played a major role in the history of astronomy and navigation, and is best known as the location of the prime meridian.
The working institution moved from Greenwich to Herstmonceux after World War II
And the Greenwich site is now maintained as a museum.
Rosalind has already very kindly explained "Canary" Wharf to you!
More specifically, Canary Wharf takes its name from No. 32 berth of the West Wood Quay of the Import Dock.
This was built in 1936 for Fruit Lines Ltd, a subsidiary of Fred Olsen Lines for the Mediterranean and Canary Islands fruit trade.
At their request, the quay and warehouse were given the name Canary Wharf.[8]
"The Pencil Point" and the "Gherkin" are very tall buildings at Canary Wharf, so "called" because of their shape against the sky line!
I hope that is of some help?
I am now away to my bed!
