London - July 1969

 Top deck of the Number 11 Routemaster.

 The only description on this photo was - 'East London, outside Billingsgate Fish Market' -  I needed a lot more information, such as - What are all those people up to?  Why did we take this photo, it's pretty boring.

So today I've been Google searching and found the Billingsgate Fish Markets which are now enormous and way away from the other photos of the day such as the Tower and Bridges, so I Googled further peered at the photo closer and found the 'Old Billingsgate Markets' which is a beautiful old building in Lower Thames Street right near a little Church.

So...  I reckon that's a wedding going on outside that Church on the left, or was it just a Sunday and the crowds were pouring out... Nah I think it must have been a Wedding, why else would we take this photo?  I found the same Church in the Google photo below, which is called 'Friends of the City Churches'.

 Tower of London.

 The plaque says... Bronze Gun. Dated 1464.   Cast for Mahomet 11 of Turkey by the Gunfounder Munir Ali, Calibre 25 inches. Weight approximately 18 tons... and I can't read the rest but Wiki to the rescue see below!

I was Google Earthing to see if I could find this Gun somewhere around the Tower of London which was impossible...  then with further searching found it's been moved to Portsmouth!

(The Dardanelles Gun was cast in bronze in 1464 by Munir Ali with a weight of 18.6 t and a length of 518 cm, being capable of firing stone balls of up to 63 cm diameter.^[1] The powder chamber and the barrel are connected by the way of a screw mechanism, allowing easier transport of the unwieldy device.
Such super-sized bombards had been employed in Western Europe siege warfare since the beginning of the 15th century,^[5] and were introduced to the Ottoman army in 1453 by the Hungarian gunfounder Orban on the occasion of the Siege of Constantinople.^[6] Ali's piece is assumed to have followed closely the outline of these guns.^[6]
Along with a number of other huge cannon, the Dardanelles Gun was still present for duty more than 300 years later in 1807, when a Royal Navy force appeared and commenced the Dardanelles Operation. Turkish forces loaded the ancient relics with propellant and projectiles, then fired them at the British ships. The British squadron suffered 28 dead through this bombardment.^[4]
In 1866, on the occasion of a state visit, Sultan Abdülâziz gave the Dardanelles Gun to Queen Victoria as a present.^[6] It became a part of the Royal Armouries collection and was displayed to visitors at the Tower of London and was then moved to Fort Nelson at Portsmouth.^[7]

 London Bridge being dismantled before being shipped off to Arizona. It was bought by Robert McCulloch from the City of London.  McCulloch had the exterior granite blocks numbered which then clad his bridge in the planned community of Lake Havasu. 

It is a popular rumour that the bridge was bought in the belief that it was London's more recognizable Tower Bridge but this was ardently denied by McCulloch himself and by Ivan Luckin, who sold the bridge.

 London Bridge today sitting comfortably in Lake Havasu, Arizona.

And the very beautiful Tower Bridge below.
