Heritage Open Days
Heritage Open Days is an annual celebration of England's history and culture that allows visitors free access to heritage sites and community events that are not usually open to the public, would normally charge an entrance fee, or that are hosting an event for the festival. It takes place in September.
Heritage Open Days was established in 1994 as England's contribution to European Heritage Days, in which 49 countries now participate. It is one of England's biggest voluntary cultural events, attracting some 800,000 people every year and bringing together over 2,500 organisations, 5,000 events and 40,000 volunteers.
The equivalent event in Wales is Open Doors, in Scotland Doors Open Days, and in Northern Ireland European Heritage Days. Open House London is also part of the initiative and takes place in September.
