England’s largest festival of history and culture, Heritage Open Days is back for 2025, from 12 – 21 September.
Presented by the National Trust, supported by players of People’s Postcode Lottery and run by thousands of local organisations and volunteers, Heritage Open Days gives everyone the opportunity to enjoy free access to experiences and events across England.
The festival brings people together to celebrate their heritage, community and history. Each year places across the country, including many National Trusts sites, throw open their doors to give people the chance to explore, see hidden places and try new experiences for free.
This year’s theme is Architecture, delving into the stories, history and impact of the buildings and structures around us.
