Harmony Grove Missionary Baptist Church was founded in 1871 when local businessman William Koehl donated one acre north of Huntsville for the establishment of a church for the African American citizens of Pine Prairie. The leading founders of the congregation were deacons W.T. Watkins and Matthew Bryant, and the Reverend W. Watkins. A small church building was soon constructed and was also used as the home of the Pine Prairie school. Church trustees later purchased two additional acres from William Koehl’s son, Herman, in 1901. On June 24, 1978, the Harmony Grove Missionary Baptist Church burned to the ground. John Kay, a concerned neighbor, saved the church bell from the fire. The bell was later restored and is displayed in front of the rebuilt church. Congregation members worked hard to rebuild the church, and a building in which to hold services was soon located and moved to the church property. In 1991, a house was donated to the church and also moved to the property. Once renovated, the new building provided a new sanctuary, choir stand, pastor’s study, fellowship hall, kitchen, restroom and storage space; the entire structure was remodeled in 1999. Harmony Grove Missionary Baptist Church was Pine Prairie’s only African American church for over 100 years. During its existence, the church has developed a youth ministry, a nursing home ministry and a prison ministry. An annual homecoming is held each fourth Sunday in August, and a church picnic is held each May. Through its community outreach and mission work, Harmony Grove Missionary Baptist Church continues to positively impact its community.
