Heritage Open Days is an annual event in the United Kingdom that celebrates the country's rich history and culture. During this time, historic buildings, landmarks, and sites that are usually closed to the public open their doors for free. The event encourages communities to explore their local heritage and learn about the significance of these places. Typically held in September, Heritage Open Days involve guided tours, exhibitions, and activities for all ages. It aims to promote awareness of local history and foster a sense of pride in the cultural heritage of different regions. Participants can discover unique stories and experiences tied to their communities.
