Inside the Tower of London

Raven chicks are born in the tower for the first time in 30 years - but only one of the newborn birds can stay, and ravenmaster Chris faces the tough decision of choosing one to keep and finding suitable homes for all the others. The tower director prepares to retire after 15 years, and takes a moment to enjoy his final gun salute, while AJ Clarke, only the second woman to join the Yeoman warders, embarks on a fitness regime that soon leaves her in need of a new uniform. Plus, a look at the story of the time the future Queen Elizabeth I was imprisoned in the tower for plotting to overthrow her sister, Queen Mary.

The chief yeoman warder oversees the tower's celebration of the end of the First World War, and special preparations are made for the tower director's retirement party, involving a military band and a unique farewell as he leaves the tower for the last time. Newly hatched raven George is introduced to the rest of the birds, not all of whom take kindly to newcomers, and historian Tracy Borman unearths the story of Roger Casement, who was executed for treason for supporting Irish independence during the First World War.
