Why it's listed

Mount Lookout, known as the McPike House, is a sixteen-room red brick mansion on a hilltop in Alton, Illinois. Completed in 1871 after three years of construction, it was designed by regional architect Lucas Pfeiffenberger for Henry Guest McPike. The house combines a concave mansard roof, round-headed windows, a Palladian center dormer, decorative eave brackets and a vaulted limestone wine cellar. It once stood on a 15-acre estate of vineyards, orchards and rare shrubs; 4.4 acres remain. McPike was prominent in Alton's business, political and cultural life. He served as mayor, developed a corrugated paper machine that grew into a large box factory, bred the McPike grape, and was a friend and associate of Abraham Lincoln. Pfeiffenberger headed an Alton firm whose work spread across the Midwest, and this house is counted among his finest designs. The McPike family lived here until 1936. A business college and later a multi-family dwelling followed, and the house has stood empty since the 1950s, with mantels and staircase lost to thieves and vandals.

Significance in brief: The nomination calls it a fine example of the Second Empire Italianate style and one of the best works of architect Lucas Pfeiffenberger. It is also tied to Henry Guest McPike, an Alton industrialist, horticulturist, mayor and Civil War provost marshal who knew Abraham Lincoln.

What listing means for this property

National Register listing is honorary: it recognises significance and does not restrict what a private owner may do without federal money or permits. It unlocks the 20% federal rehabilitation tax credit for income-producing buildings, state credits in many states, and Section 106 review when federal agencies are involved. See what listing means in practice.
