Heritage Open Days is England's largest festival of history and culture, involving thousands of local volunteers and organisations.
The festival takes place between September 12 to 21, and there are a range of activities for you to enjoy.
Every year the festival brings people together to celebrate their heritage, community and history – offering the public a chance to see hidden places and try out new experiences.
This year the theme is architecture.
Now into its 31st year, this year’s event sees more than 5,800 free events taking place at a wide range of much-loved venues and heritage sites across the UK – as well as hidden gems that are usually closed to the public.
Liam Montgomery, Heritage Open Days marketing and projects manager, said: “2025 is set to offer the most ambitious and wide-reaching Heritage Open Days programme yet, and it’s brimming with great things to do.
“Whether it’s well-known landmarks and hidden architectural gems or community-led talks and immersive experiences, the sheer diversity of places and stories on offer is extraordinary. It’s a testament to the passion and dedication of local organisers and volunteers who make this celebration of our shared heritage possible.”
