A meetinghouse, meaning a building for religious assembly, was the term used in the Book of Records of Mill Creek Baptist Church for its place of worship. After settlers arrived in Monroe County, homes, barns, and businesses took priority, so the church first met in members' homes. By 1798 the congregation had grown too large for local houses, and a first meetinghouse was built about 600 feet west of the current building. Under John Mulkey's leadership the congregation flourished, and by 1804 it decided to build a larger meetinghouse. A seven-member committee of John Wood, Nathan Breed, James Harlin, Ephraim Ellis, Frances Baxter, Joseph Guest, and Thomas Sullivant was appointed to prepare a building plan, and its report set out the structure's size, shingles, doors, windows, and financing through subscriptions and payment of the debt as funds became available. Although the plan did not state a shape, the building was erected in the form of a cross. When the building was five years old, it housed the heresy trials of John Mulkey by Mill Creek Baptist Church. As a result, it became the home of the first Christian Church in south central Kentucky, later known as Mulkey's Meetinghouse. John Mulkey and his followers met there until 1850, when they abandoned the site for unknown reasons, and without a congregation the building fell into disrepair. In the late 1870s local residents renovated it, adding a new clapboard roof and a split-rail fence around the cemetery, and interested citizens carried out a second renovation by 1890. After that it was used for weekly religious meetings and singing but was abandoned again around 1910. In the summer of 1925, Joe H. Eagle, a United States Representative and Monroe County native, visited with Willie Thomas of Tompkinsville, and their concern led to the formation of a Board of Trustees to oversee a third restoration. After that work returned the building to its original form, local trustees sought lasting protection through the Kentucky state park system, established in 1924. In November 1931 the site was dedicated as the ninth property in the Kentucky State Parks, with approximately 4000 people attending. Electricity was added later. In the winter of 1995-1996 the building was raised and a stone foundation built beneath it. By 2007 the benches had become a safety hazard, and students from the carpentry class at the Technology Center helped replace them; three years later, in a special ceremony, they installed the last new benches, whose hand-worked legs echoed the methods used more than 206 years earlier.
