Like many Victorian-era styles, Italianate emphasized vertical proportions and richly decorative detailing. It was found on residential, commercial, and industrial structures throughout Colorado from about 1870 until the turn of the century.

Italianate is characterized by a low-pitched hip roof, wide overhangs, bracketed cornices, a variety of fenestration (usually very tall, narrow, double-hung, one-over-one windows), molded window surrounds, and occasionally a cupola or balustraded balcony. Simple Italianate structures have a hip roof, bracketed eaves, and molded window surrounds. A more elaborate or high style example may feature arcaded porches, corner quoins, towers, and ornate detailing.

There are also some Italianate structures that are flat roofed, with a front bay and entrance, and a decorated cornice.

These photos depict some designated landmarks in Longmont that are representative of the Italianate style.
