Harmon Museum & Art Gallery

The Harmon Museum & Art Gallery is housed in Harmon Hall, an historic, three story, 28,000-square-foot brick building located in downtown Lebanon. Harmon Museum & Art Gallery is both a history museum and an art museum. It contains paintings, decorative arts and historic collections from prehistoric eras to the mid-20th century. Harmon Museum & Art Gallery also includes the Warren County Historical Society Historical Research & Genealogy Library.

Harmon Hall was built in 1913 as a recreation center and donated to the City of Lebanon by William Elmer Harmon, real estate mogul and philanthropist. Harmon was born and raised in Lebanon and complained there was no place to play when he was a child. He gave Lebanon Harmon Hall, Harmon Park, Harmon Golf Course and endowed the Harmon Civil Trust to maintain the properties.  In 1961 Harmon Hall became the home of the Warren County Historical Society Museum. In 1979 the Harmon Civic Trust deeded the building to the Warren County Historical Society.  The Historical Society changed the name to Harmon Museum & Art Gallery in 2017 to better reflect the museum’s collections and to honor Mr. Harmon.
