Our Partners

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

Our lead sponsor is Winchester College, who are also hosting eleven events of their own this year. 

Locally we are also supported by hundreds of organisations, businesses and volunteers who manage and promote their individual site openings and events, and it is thanks to their commitment and hard work that last year the festival attracted around 10,000 visits.


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.
