Perry County was established by an act of the state legislature signed by Governor William Findlay on March 22, 1820. Landisburg was the first county seat. The first court house, a log building located northeast of Trinity United Church of Christ, was rented by the county for $50.00 a year, and all other county offices were located in the homes of the officials. On March 22, 1970, a sesquicentennial commemorating Landisburg as the first county seat was held at Trinity United Church of Christ on a cold snowy day, with warmth abundant in the hearts of all who attended in appreciation of their freedom-loving ancestors.
