In this new six-part series, architectural historian Simon Thurley goes in search of some of the most amazing buildings ever built in Britain. The only problem is that none of these structures are still standing...

With the use of dramatic reconstructions, archive research and computer simulations, Thurley and a team of experts and historians take on the challenge of recreating six amazing buildings that have gone forever, seeking not only to bring them vividly back to life, but to establish without doubt their historical significance.

Featuring trips to Oxford and Sweden and the world's oldest working theatre, Thurley reveals the hidden narratives behind what we have lost from our historic landscape and persuasively demonstrates the architectural and cultural importance of these great, lost British buildings.
