Free Heritage Open Days are back! England's largest festival of history and culture is returning in September.

You can explore the places and spaces on your doorstep at various venues in Hertfordshire, including events as varied as a free medieval cookery demonstration at Berkhamsted Castle to visiting a working watercress bed.

Thanks to support from players of People’s Postcode Lottery, residents and visitors will be able to try new experiences across the region between September 10 to September 19, 2021.

Many events will explore this year’s theme of Edible England, offering opportunities to learn about food production, celebrate local specialities and uncover the customs and quirks around what we eat and drink.

Sarah Holloway, programme manager for Heritage Open Days, said: “We’re all interested in where we live but we don’t necessarily know the stories behind the buildings and spaces we walk past each day.

"Our event organisers keep finding creative ways to tell these tales and keep them alive.

"HODs connects people through shared experiences and this year, that feels more important than ever. It’s also one of the reasons we chose Edible England as our theme. Food brings people together and what we eat and drink is at the heart of much of our culture, our history, our communities, and our daily lives.”

Every single Heritage Open Days event is free, including access to many sites that usually charge for admission.

Laura Chow, head of charities at People’s Postcode Lottery, said: “We’re delighted our players are able to continue to support Heritage Open Days in 2021.

"The festival has always been about bringing communities together, and this year we’re particularly excited to see how this can be done through food and drink events. It’s certainly a tasty theme!”

Heritage Open Days is coordinated and promoted nationally by the National Trust with support from players of People’s Postcode Lottery.
