Historic houses, factories, museums, music halls, formal gardens and graveyards will be among places open for free across the North East and North Yorkshire this month.

English Heritage is celebrating its 30th anniversary with more than 5,400 free open days across the country.

From September 6 to 15, the public is invited to visit heritage sites free of charge in what is described as “the country's largest festival of history and culture”.

Events, talks, and normally closed-to-the-public buildings will all be included in the annual festival of history and culture.

Laura Chow, Head of Charities at People’s Postcode Lottery which is supporting the event, said: “We are thrilled to be celebrating 30 years of this wonderful festival.

“Our players are helping to keep the doors open and free for everyone. We hope even many more people will come out to explore, celebrate, and enjoy England’s national heritage.”

This year’s theme of routes, networks, and connections explores how people and ideas have moved throughout history.

English Heritage hopes this will “bring together the past and present” through a series of talks, walks, and activities for the whole family.
