McHenry County Local Historic Landmarks

Press Enter to show all options, press Tab go to next option


McHenry County Historic Preservation Commission has designated twenty-two local historic landmarks since the Commission's inception in 1991. All the landmarks designated since 1991 remain intact with the exception of one  – the Allendale Truss Bridge.  This structure was removed due to safety concerns in 2009 and replaced with a modern bridge structure.  The Commission has designated this landmark as "lost," but we still maintain the information relevant to its former landmark status.  

The Commission has jurisdiction over unincorporated areas of McHenry County; although some landmarks have been designated through intergovernmental agreements with municipalities, while a few have come under the jurisdiction of municipal historic commissions after the County had designated them. We continue to list those landmarks here with an annotation regarding the applicable status change in the listing details section. Several of McHenry County's municipalities conduct their own historic preservation programs, and the county is home to many not-for-profit historic-interest organizations. Please see the "Links" section for further information on these cities, villages, and organizations.  

Detailed information about each one will be added in the future.

Woodstock and North Streets in Huntley are one of the few remaining examples of brick streets containing old paving bricks in McHenry County.

The Frank and Louisa Newman house was built of brick in 1873 in the Italianate style. Newman and his father-in-law, Washington Hammond, were both brick masons and thought to have operated a brick yard and kiln on site.

Chief Big Foot of the Pottawatomie Indians who formerly lived on the surrounding prairie, came back several times as a houseguest of Hutchinson. This brick house is of the Gothic Revival style with its steep-pitched roofs and decorative finials at the peek of each gable. It is also referred to as the house of seven gables since each finial represents one of seven zodiac signs.
 William Coventry House

William Coventry House
Chemung Township
in the City of Harvard

Coventry Farm was once crossed by Indian trails and roamed by deer and wolves.  Initially, two 40-acre homestead parcels were deeded to Franklin Smith in the 1840s. William Coventry, the former captain of a whaling ship, arrived from New York in 1844, and he had the first parts of today's house and barn built in 1855. William Coventry left for Minnesota circa 1871.  David Coventry and Ida May (Smith) were married in 1871 and lived in the house with Ida May's parents.  Around this time the house and barn were expanded.  The couple inherited half her parents' estate by 1901.  Soon thereafter, they purchased Horace Smith's share and the property became known as the David Coventry Farm.
