Built by volunteers in 1869, the Union Meeting House was the second "house of worship" on the land which was "eight rods wide and eight rods deep fronting on the highway." It was owned by Methodists and Free Will Baptists. Completed in 1870, the villagers were proud of the new building with its tall weathervane on the bell tower, which afforded a spectacular view of the Huntington valley.

The bell from the first meeting house, cast in 1837 by Meneely & Oothout, proclaimed the hour for worship as well as tolling a call to volunteer firefighters that was heard throughout the valley.

By the turn of the century, the Methodist Episcopal Society ceased to exist and the building was owned by the Baptists. In 1964, the two Baptist congregations in Huntington voted to become the United Baptist Church of Huntington and Huntington Center and worshipped alternate weeks in either church. In the late 1970s, the congregation determined it was too costly to maintain two buildings.

The Union Meeting House was purchased in 1985 by the newly-formed Huntington Historical Society. Through their efforts, much work has been done to the building. In 1984, the Union Meeting House officially entered on the National and State Register of Historic Places.

Over the years, many beautiful and useful gifts were donated to the Union Meeting House. Some are used today in the Huntington Baptist Church in Huntington Center. Others will remain in the UMH as part of the finished renovation, which will feature historic details of the building as well as modern conveniences.
