Discover more about Hertfordshire's wealth of fascinating places and spaces, with this year’s Heritage Open Days.

The September festival brings people together to celebrate heritage, community and history in England – and all for free. A wide range of organisers that usually charge for events, free sites that put on extra special events for the festival and places that aren't usually open to the public will take part again this year.

The event has captured imaginations for almost 30 years. Last year more than 2,150 organisers along with 43,500 volunteers ran nearly 5,000 events across the country, attracting one million visits. Around one-third of visitors had not visited a heritage site/event in the past year while eighty percent of people said their visit made them proud of their local area.

Heritage from historic houses to factories, museums to music halls, formal gardens to graveyards and places and spaces in between, will be opening their doors. The festival will also celebrate the stories and work of the experts and enthusiastic amateurs who add that something extra to places around the county. This year’s theme is Creativity Unwrapped so there’s a special emphasis on artists, makers and inventors.

Liam Montgomery, Heritage Open Days marketing and projects manager, says: ‘Whether it is art, music, writing, or another outlet, creativity moves us and shapes our history and culture. We’re excited to put the spotlight on the people and places who give England’s heritage the X-factor and inspire festival-goers to engage with thousands of years of creativity.’

It’s a chance to take a sneak peak of some of England’s hidden heritage and this year discover its colourful history of creativity. Here are a few of the open days, events and experiences being held around Hertfordshire.
