Our Partners

Winchester
Locally, we are supported by hundreds of organisations, businesses and volunteers who programme, fund, manage and promote site openings and events. Last year the festival attracted around 10,000 visits thanks to their commitment and hard work.

The festival team are all volunteers from the City of Winchester Trust, who also provide us with office space and support.

Nationally
Heritage Open Days is coordinated nationally by the National Trust with support from players of People’s Postcode Lottery. At grass roots level the festival is organised by over 2,000 organisations and some 40,000 volunteers who share a passion for places, history and culture. Jointly attracting over 3 million visitors, they make Heritage Open Days England’s biggest voluntary cultural event.
