Abigail Whelpley House // c.1826

The oldest extant building on Hillhouse Avenue in New Haven is this Federal-period house with later Victorian-era modifications. The Abigail Whelpley House was built by 1826 (with some estimates as early as 1800 and moved to the site) and was a traditional, five-bay, two-story Federal style residence. It is said that the house was built by James Abraham Hillhouse (1789-1841) for his widowed family member, Ms. Whelpley, and her two sons. As of 1849, the property was owned by Noah Porter, later President of Yale, who would alter the house in the 1860s with the addition of a mansard roof and trim, all designed by architect, Henry Austin. The house, now known as Allwin Hall, is maintained by Yale University and contains offices for the program on Ethics, Politics & Economics.

Graves-Dwight House // c.1862

Hillhouse Avenue in New Haven, Connecticut is lined with stunning 19th- and 20th- century mansions showcasing the evolution of styles and architectural taste for the wealthiest residents. This is the Graves-Dwight House, a high-style Italianate mansion built around 1862. The residence was built for John Samuel Graves (1807-1892), a local businessman and politician who was a founder of the New Haven Gas Light Company. The architect is not known, but the house is the work of a skilled designer with immense attention to detail. The highly ornamented exterior features a symmetrical facade, bracketed cornice and window hoods, a recessed third-floor balconette with segmental arch pediment above, and bold, period-appropriate paint scheme. The residence was later owned by James McLaren Breed Dwight, a lawyer, and his wife, Cora Tallmadge Dwight. Since the 20th century, the property has been owned and preserved by Yale University, and is now home to the Archaeology Department.

John E. Calhoun House // c.1912

This site, in the heart of Cornwall village, was once occupied by an early 19th century Federal style residence, built by the wealthy Pierce family in town. The Pierces’ large home was acquired by John E. Calhoun (1859-1940), a successful New York businessman, who retreated to his father’s hometown for summers away from the city. In 1911, a fire destroyed the home, which was wood-frame construction. This event mobilized Mr. Calhoun, who was untrained but interested in architecture, to begin planning a new summer residence, but of fireproof construction. Calhoun is said to have designed (and funded) the town’s library just years before, and modeled his home in line with the Colonial-era residences in the village, just larger and of brick. From the 1950s through the 1990s, the house was occupied by the headmaster and administration of the local Marvelwood School, but was re-established as a private home, a use that remains today.

Harriet Bennett House // c.1912

While most houses I have featured in Cornwall date to the early-mid 19th century, there are some great examples of early 20th century Colonial Revival dwellings, built at the time the town became eyed as a wealthy retreat for city-folk. This Colonial Revival residence was built for Ms. Harriet Bennett (1841-1928), an ardent suffragist and an active member of the Connecticut Woman Suffrage Association. Harriet was married to William C. Bennett and after his death in 1898, she devoted the rest of her life to charitable causes and giving back to others. As a widow and in her seventies, Harriet oversaw construction of this house, which was completed by 1912, in that same year, established the Cornwall Equal Suffrage League, hosting many of its events and meetings from this house. The League’s activities mirrored the efforts of suffragists throughout the nation. The house remains a well-preserved example of a house in the Colonial Revival style in town.

Dwight W. Pierce House // c.1850

On land he acquired from family, Dwight Wellington Pierce (1816-1901) erected this large, temple-front Greek Revival estate just outside Cornwall Village in Litchfield County, Connecticut. Mr. Pierce farmed this land and built barns across the street from his residence on Popple Swamp Road, where he kept his livestock. The Pierce house is unique in Cornwall as a temple-front Greek Revival style house and features a two-story portico with four Doric columns, the center two are rounded and fluted with the ends square. The elongated house is seven bays wide and must have been quite the sight when it was built in the mid-19th century.

General John Sedgwick House // 1860

The Major General John Sedgwick House is located in Cornwall Hollow, Connecticut, and stands out as one of the finest residences in this part of the state in a rural setting. The house was built by 1860 for General John Sedgwick (1813-1864), who was born in a house standing on this site, which had been built by his grandfather, a veteran of the Revolutionary War. In 1859, the Sedgwick family homestead burned to the ground. Sedgwick, then already well established in his military career, took leave to oversee construction of its replacement. This house was built, apparently on the foundation of the old house, in 1859–60. The work was done by Cyrus Marsh, a local builder, in the Italianate style with decorative brackets, window mouldings, hoods, and a large columned entry portico. Major General Sedgwick was active in many campaigns, and during the American Civil War, he was killed by a sharpshooter at the 1864 Battle of Spotsylvania Court House, he was the Union Army’s highest-ranking casualty of the war and never got to reside in his Cornwall home.

Hidden Valley Castle // 1921

Photo from listing.

A castle can be found in the small town of Cornwall, Connecticut! Set amongst 275 acres of woodland and streams, with several outbuildings on the property, this whimsical castle looks like it was dropped here from Cornwall, England, but it actually dates to the 1920s. Hidden Valley Castle, had its beginnings when socialite Charlotte Bronson Hunnewell Martin envisioned building a unique country retreat for herself and her husband, Dr. Walton Martin, in the Litchfield Hills of Connecticut as a summer retreat. Just before this, Charlotte had bought a group of 20 brownstones in Manhattan on 48th and 49th Streets, between Second and Third Avenues, and converted them into charming townhouses around a central Italian-inspired garden. Called Turtle Bay Gardens, the houses were highly acclaimed and almost immediately attracted prominent and celebrated residents. The Cornwall Castle was designed by architect, Edward Clarence Dean, who also redesigned the Turtle Bay Gardens for the couple. Dr. Martin imported many of the materials as well as the 100 workmen required to build the castle, a project that lasted five years. Charlotte would also have a cottage built on the estate and hired young Italian artist, Vincenzo Rondinone, to be her resident artist on the estate to create unique vases, bowls, and pots to be used at the house and to be given as gifts to visitors and friends. The property was restored in recent years and put up for sale, with the cottage sold as a separate dwelling.

West Cornwall Congregational Church // 1877

One of the few Gothic style buildings in the enchanting town of Cornwall, Connecticut is this large church-turned-residence in West Cornwall village. As West Cornwall developed in the second half of the 19th century into the largest district in town, residents here began to discuss the idea of building their own Congregational church, rather than travel to the central village church to attend services. In the 1870s, West Cornwall congregationalists raised over $4,000 to acquire a building lot and erect this fine church. Dedicated in January 1878, the wood-frame church is a rare example of the Victorian Gothic/Stick styles with clapboard siding, lancet (pointed arched) windows, a corner tower with belfry, vertical sheathing in the gables, and ornamental applied stickwork. The church closed in the 20th century and was converted to a private residence, and is presently for sale!

Foster Mansion // c.1860

This large, Italianate style mansion is located at 417 Sharon-Goshen Turnpike, the main street through West Cornwall Village, Connecticut. The house was built around 1860 for Stephen Foster (c.1816-1863) a merchant and railroad contractor who had constructed a portion of the Housatonic Line railroad near West Cornwall. He and his wife, Helen, previously lived in a Greek Revival style house across the road until they moved into this stately residence. Mr. Foster would not get to enjoy his mansion long as he died in 1863. Helen Foster remained at the home until her death in 1875. The high-style Italianate residence was likely built by master-carpenter C. W. Marsh, and features all the hallmarks of the style: overhanging eaves with decorative brackets, elaborate window and door moulding, two-over-two windows, and a shallow hipped roof with dormer.

Foster-Beck House // c.1845

This attractive Greek Revival style residence with later porch was likely built in the 1840s and is one of the finest homes in the village of West Cornwall, Connecticut. The house was likely built for Stephen Foster (c.1816-1863), a merchant and railroad contractor who had constructed a portion of the Housatonic Line railroad near West Cornwall, further opening the village up to trade. Stephen and his wife, Helen, lived here for some time until around 1860 when they relocated to a larger, Italianate style mansion nearby. In 1867, this property was purchased by George Beck, a German immigrant and partner of the Vollmiller Shear Shop, who manufactured metal shears and scissors in West Cornwall. It is likely that Beck was owner of the house at the time the wrap-around porch with scroll-sawn columns.
