Running from September 12 to 21, the annual event sees scores of fascinating historical buildings open their doors for visitors to explore for free.
In Wakefield, there are lots of venues taking part.
Visitors can explore church buildings that are hundreds of years old, delve into intriguing histories with expert-led talks delivered specially for the festival, and go behind the scenes in areas of venues usually off-limits to the public.
The festival is delivered by the National Trust and supported by players of People’s Postcode Lottery.
Laura Chow, Head of Charities at People’s Postcode Lottery, said: "Heritage Open Days bring communities together in a truly unique way, shining a light on the stories, spaces and skills that shape our shared history.
“I'm delighted that support from players of People’s Postcode Lottery helps make this vibrant celebration of culture and creativity accessible to everyone, inspiring new generations to connect with the heritage all around them."
