Gov. Bruce Rauner and first lady Diana Rauner are officially reopening the Illinois Governor’s Mansion after a more than two-year renovation.

A grand re-opening is scheduled for Saturday at the historic Springfield residence. It will include a morning ceremony and public tours of the mansion.

A privately funded, roughly $15 million renovation began in early 2015. It included installing a new roof, HVAC system and entrance. Work also was done to ensure the mansion complies with the Americans with Disabilities Act.

The mansion now has a new visitor center. Guests also may view artwork and several exhibits, including one on Illinois life during the Civil War.
