Area residents will be able to tour 11 sites across Sarnia-Lambton and get a behind the scenes look.
Doors Open Lambton is on Saturday.
Manager of Museums, Gallery and Archives Laurie Webb said it's an opportunity for people to see things and places they normally wouldn't have the chance to.
"Specifically historic homes, buildings, businesses and different organizations involved in preserving the heritage of the county and it's all free, " said Webb.
Webb said some of the locations that have tours include the Oil Museum of Canada, CEE Hospital Board Room and the Henry T. Ross Substation.
