Heritage Open Days are a national event in early September, and this year St. Mary's will be show-casing some of the hidden and rarely seen gems of its history. Alongside the bell-ringers talking about the history of the bells and inviting visitors to 'have a go', there will be rarely seen books, papers, pictures, and artifacts on display. Self-guided 'tours' will enable visitors to learn about how the building developed over the centuries, and encourage them to find out more about the people who influenced the life of Eversley and its church.
