Holcombville School — McHENRY COUNTY HISTORIC PRESERVATION LANDMARK In 1858 one-half acre of land was purchased by the school directors from Sutherland Ingersoll for $12.25. This one-room schoolhouse was named after the Holcomb family that lived nearby. It operated as a school until 1946 when it closed due to consolidation. The school was built out of brick with the decorative brickwork at the cornice to represent dentils and cornice returns. It has never been converted to alternate uses and is in the original condition.
