Award-winning actress Jenna Coleman has given fans a glimpse at the filming of the latest series of Victoria.
ITV film crews were spotted at the National Museum of the Royal Navy in Hartlepool on Tuesday - but museum staff were unable to confirm to the Mail what was being filmed.
The town has played host to the channel's hit series Victoria before, and work began on the filming of series three in May.
Jenna Coleman, who has played the monarch since 2016, took to her Instagram stories to share some "at work" snaps with her followers.
In the photographs, you can clearly see the HMS Trincomalee. Her account has more than 765,000 followers.
The Museum of the Royal Navy was closed to the public on Tuesday, but is set to be open as normal today.
Speaking to the Mail, Roslyn Adamson said: "We are proud of the museum’s historic attractions and assets, and are often approached for them to be featured on various media platforms, including film and television.
“Film and television tourism is another effective means of boosting revenue by attracting more visitors to the museum site, so we always try, where possible, to seek out relevant opportunities and accommodate these kind of requests."
Series three of Victoria will be an eight-part drama, starting in 1848. ITV have not yet confirmed a start date.
