Over six hundred historic photographs of London, never seen in public before, have been published for the first time.
The images were discovered by archives manager, Stefan Dickers at Bishopsgate Institute.
He found boxes containing over 3000 slides.
The collection features images of most of London's landmarks, churches, open spaces, statues and buildings, alongside social and cultural scenes from the Victorian to the inter-war period.
A project was launched to digitise the images in 2007, and now they've been printed for the first time.
Here are some of the highlights of a slice of London history.
The entire set of images are published in The Gentle Author’s London Album, published today.
