The BBC is to reveal some of the secrets of its world-famous Natural History Unit (NHU) to the public.

The Bristol-based NHU is known for television hits such as the Blue Planet, Life on Earth and Big Cat Diary.

Now, for the first time since it began 46 years ago, viewers will be able to attend a special day event to see how the programmes are put together.

The BBC's nature programmes are among the most popular with its viewers and are sold around the world.

The Natural History Festival on Saturday 31 May will feature sneak previews of new programmes and lectures and features on how series were made.

There will also be question and answer sessions with the film-makers themselves.

Neil Nightingale, head of the NHU, said: "It is a chance for the public to help celebrate the success of the unit and for us to say thank you to them for their ongoing support and interest in our work."

The event is being held in the Harbourside area of the city centre.
