Signs of Zodiac - Bracken House - Cannon Street, London, UK - Signs of Zodiac on Waymarking.com

It is not only a clock but a calendar as well. The date is shown in a small window below the sun at the centre of the clock. The months of the year are shown around the outer edge of the zodiac signs. The month and time are all defined by the pointer at the top of the face. The lower part of the pointer shows the current month and star sign. The large window in the pointer shows the hour or, if not on the hour the space between them. Around the outer edge are the minutes with the five minute intervals being indicated with numerals. With there being no hands, all the parts rotate anti-clockwise to display the month, star sign, hour and minutes.

The Tea Time in Wonderland website tells us:

Rather than rushing to the underground tunnels, jump in one of the vintage buses leaving from Trafalgar Square. Yes, real routemasters! With their rounder angles, their bright ruby red, they bring a smile to the lips, like meeting an old friend. Even better, it will not cost you more than a normal bus fare and you can use your Oyster or Travel card… Two lignes depart from the square, #9 and #15. Prefer the latter which will take you up to the Tower of London.
 
You will drive through Fleet Street – look at the richly sculpted buildings, the Court of Justice… It was home to the most famous newspapers at one time. The second biggest river of the City (the first being the Thames, of course), Fleet, actually runs underneath. A few minutes later, you will be at St Paul’s – splendid view if you are on the deck level, worth a picture. Just after the cathedral look out on your right for the Bracken House. The building may not look like much, with its brick walls but what an entrance with this one meter wide astronomical clock!
 
Bernard Bracken was pretty powerful in its time – chairman of the Times, no less! - and had it installed in 1955. The paper was printed here until 1980 when new techniques forced a move to the Docklands.
 
The clock shows the time, date and zodiac signs in touches of blue enamel and gold metal. But focus on the centre - see the serious, almost stern face? This is Winston Churchill’s, personal friend of Bracken’s (who, by the way, worked for the politician as his Minister of Information). What a great proof of friendship and support to picture him as a sun God!
