As big as...

Seven houses. This is how tall Della thought Big Ben might be, I checked it's more like 15 houses. Never the less Big Ben was her favourite sight in London. After lunch in central hall

And a dance to the bells at Westminster abbey 

We eventually found her holy grail and she was giddy! 

They a stroll over the river to see the Thames and a walk down Whitehall to get as close as you dare to some massive horses

And casually chat war and death (which she already understands thanks to Remembrance Sunday and yearly briefings from nursery and school) at the cenotaph whilst explaining some women have their own statue 

Oh and Downing Street where the silly man with the little red bag is sometimes seen but mainly fascinating because the special gates 

Then it was into our last leg...
