Inside One of London's Oldest Medieval Crypts

If you imagine a Catholic military order from the Middle Ages, it’s likely to be the Knights Templar - popularised by Dan Brown’s fictional thriller, The Da Vinci Code

But in Medieval Europe, there was another, equally powerful religious society, which also had its English headquarters here in London. It was the Order of St John of Jerusalem. Better known, as the Knights Hospitaller.

In today’s video we will explore the history of the Order of St John, visiting their base of operations here in Clerkenwell, London. The priory is one of the city’s hidden gems, with surprises around every corner.

Formed in Jerusalem in the 11th century to care for pilgrims, the order went on to become an ambitious military organisation, owning lands and wielding influence across Europe.
