The annual Heritage Open Days event is a chance to go behind-the-scenes at some of the Cotswolds’ most interesting historic buildings. This celebration of local heritage lets you explore some venues which aren’t normally open to the public and saves you money with free entry to others.
This year’s Heritage Open Days takes place between 8 and 17 September 2023, with over 5000 events taking place across the country. A range of churches, priories, country houses, schools, factories, mills and gardens are taking part. There’s a mix of guided tours, walks, talks, workshops and special events – as well as free entry to several National Trust and English Heritage sites.

The event has been running for over 30 years now and is still going strong – this year’s theme is ‘Creativity Unwrapped’, with a focus on the history of creativity in England.
So if you are planning on visiting Heritage Open Days in the Cotswolds this year, here’s our pick of 18 of the best events taking place – you can find the full list on the Heritage Open Days website. Many you can just turn up to, but some of the tours do need to be booked in advance.
