Whilst reading an article on the 14 useful products that Google offer. I found this really useful link to the Google Cultural Institute and English Heritage which I thought was share-worthy.
It covers a wide range of English heritage including the hidden history of English heritage told by Dan Snow.
It also covers the journey from the Romans to Banksy entitled the long-forgotten history of graffiti. There are lots of content and some fantastic images and video about the history and heritage of England including a walkthrough video of Stone Henge. You can also discover an in-depth view of the York Cold War Bunker built in 1961, and lots more. A good read for all.
