This “little gem of a stone church,” built and dedicated in 1893, is constructed of locally quarried, rusticated Berea sandstone blocks. A Celtic cross at the top of the west wall represented the areas of Great Britain from which many original parish members immigrated to this area of Ohio. The chapel is named in honor of John Ogilvy. He was not a member of St. Thomas Church, but he did leave a bequest which the parish used to erect the chapel. It was constructed at a cost of $4,174.70.
