Harmon Museum

Harmon Museum (commonly referred to as the "Lebanon Museum") is housed in historic Harmon Hall. Harmon Hall was built in 1913 as a recreational facility by real estate mogul and philanthropist, William Elmer Harmon, and donated to the City of Lebanon. 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 (he established more than 120 across the country), Harmon Golf Course and endowed the Harmon Civic Trust to maintain the properties. Harmon Hall was state of the art for 1913 equipped with exercise machines, a basketball court (you can still see part of the court in the General Store on the Village Green) and two lane bowling alley (now the Farm Heritage Gallery). It became a YMCA in 1946 and served as such until it was leased to the Warren County Historical Society in 1961 for its museum. The society bought the hall in 1981 and built an addition. It is now a nationally acclaimed county museum.

The Armstrong Conference Center

The Armstrong Conference Center (affectionately referred to as the "Old Post Office") was built in 1936 as a Works Progress Administration Project. It served as Lebanon's active post office from 1936 – 1998. During its life, the Post Office was also used as a designated fallout shelter. Now, it has been transformed into the Armstrong Conference Center, a beautiful and unique space, available to rent, for special events and group gatherings. This building has an indoor mural and wonderful historic architecture.

Beedle Log Cabin

William Beedle came to Turtlecreek Township (in Warren County, Ohio) in September of 1795. Along with his grown son and four son-in-laws, William first built a log block house for security against Indian attacks. Once completed, they moved on to build a church and log houses. This cabin, specifically, is of historical significance due to the fact that it was used as the location for the first Shaker meeting west of the Allegheny Mountains. 

​All the buildings fell to time except for the cabin of James Beedle. Lived in and renovated until the 1970s, it was left abandoned for nearly 50 years. When the Lebanon Correctional Institute began selling the property that used to be the Beedle land, the cabin was rediscovered and our two organizations worked together to save the structure. Now, this 225 year old log structure has been safely relocated and restored to the site next to Harmon Museum where all can enjoy this lost piece of history.
