Inside the Tower of London - Season 5

Return of the documentary going behind the scenes at the castle. As autumn arrives, the royal bodyguard of Yeoman Warders come together to commemorate one of the saddest moments in the Tower's history, the passing of Queen Elizabeth II, before announcing the formal proclamation of King Charles III.

The Tower is continuing work on its most ambitious installation ever, the transformation of the moat into a huge floral display to celebrate the Queen's Platinum Jubilee.

Ravenmaster Chris Skaife is keeping a close eye on the Tower's ravens, who are taking advantage of their popularity to steal visitors' lunches.

Deputy governor Debbie Whittingham and yeoman gaoler Rob Fuller have spotted an impressive visitor berthed across the river from the Tower – it’s a Japanese warship, which is on a world tour and is stopping off in the capital. Meanwhile, Historic Royal Palaces chief curator Tracy Borman investigates the bridges that connect the Tower to the south side of the Thames, including London Bridge and Tower Bridge.

Cameras focus on the events of June 2022, the start of the Platinum Jubilee weekend and the celebration of Queen Elizabeth II's 70 years on the throne. In the Tower's gift shop, sales assistant and royal superfan Allen Jones has been doing a roaring trade in Jubilee memorabilia. Meanwhile, senior official General the Lord Nicholas Houghton is preparing to retire. He reflects on his time living in such an extraordinary building.

On Thursday 8 September, news arrives that would change the nation's history. The death of Her Majesty Queen Elizabeth II is announced after 70 years on the throne. It's a time of deep sadness for the Tower staff and for the yeoman warders, some of whom have met the Queen in their role as royal bodyguards. As a royal palace, with special links to the Royal Household, the Tower enters a two-week official period of mourning.

The Tower has recently mourned the passing of Her Majesty Queen Elizabeth II and proclaimed King Charles III. Having seen 42 monarchs come and go, the fortress needs to make some important changes to mark the new King's reign - the Yeoman Warder's uniforms need to be updated and the Queen's House, where the Constable lives, must now be changed to the King's house.
