Morris County’s 39 municipalities are home to a fascinating tapestry of historic sites recognized on the state and national level for their significance. Some famous, some little known, together they preserve the story of the people, industries, and culture that shaped our community. In this blog series, MCHS highlights the sites to be found in each town and how they contributed to the diverse and multifaceted county we live in today.  

Coghill built both a red brick mansion and this colonial revival in Normandy Park for his children.

Normandy Park Historic District: By the late 19th century, millionaires seeking a country retreat found a new neighborhood to call home with the development of Normandy Park. In 1876, a member of a locally prominent landowning family and future president of the Morristown Land and Improvement Company, John Dodd Canfield, began acquiring land, ultimately linking property from Washington Avenue to Columbia Turnpike. Canfield intended to subdivide the tracts into a neighborhood with a park-like atmosphere centered around a main thoroughfare lined with shade trees. He started advertising the venture in 1885, and local builder George Augustus Mills received the contract to construct several of the earliest mansions soon after. Those Mills built would set the precedent for all future homes in Normandy Park, including a mandatory 200-foot setback, and the enclave’s proximity to exclusive clubs like the Morris County Golf Club further increased its desirability. Over time, it attracted a number of the well-to-do residents such as James Henry Coghill, who built neighboring homes for his children, and Alice Low Turnbull Hopkins, a well-known suffragette who graded a new road to ensure her home, Featherleigh Farms, had a Normandy Park address. While many estates have been lost over the years and replaced with modern structures, the character of the area remains largely the same, and the Normandy Park Historic District was added to the National Register of Historic Places in 1996.

Thorne and Eddy Estates: Similarly conceived by John Dodd Canfield, Normandy Heights, or simply “the Heights,” became the address of millionaires Jesse Leeds Eddy and William V.S. Thorne, whose mansions survive today. Eddy’s estate, Valley View, was also completed by George Augustus Mills in 1896. The distinct, crescent-shaped mansion included a great hall, reception room, and circular music room which featured a stained-glass dome. William V.S. Thorne enlisted famed architects Aldrich and Delano to design his neo-Georgian home on the adjacent estate in 1912. His main hall boasted Italian marble floors and a plaster frieze complete with illustrations of zodiac signs, and every room contained French doors and fireplaces. Today, the Eddy estate, as well as the carriage houses for both properties, remain private residences. Thorne’s mansion, however, is now home to the Morristown Unitarian Universalist Fellowship. Both estates were added to the National Register of Historic Places in 1978.

Whippany Farms (top photo):  George Griswold Frelinghuysen, son of US Secretary of State Frederick T. Frelinghuysen, began development of his palatial estate in 1891, purchasing 127 acres and hiring renowned Boston architects, Rotch and Tilden. The well-known firm designed a sprawling Colonial revival style mansion to be occupied by Frelinghuysen and his family each year from Memorial Day through the fall. However, the showpiece of the estate became the grounds themselves. Planned by James MacPherson, who followed the English park design that favored rolling lawns and a non-geometric layout, Whippany Farm’s landscape featured a variety of trees including silver maples, chestnuts, northern red oaks, and American beeches. Indeed, after his death, his daughter, Matilda E. Frelinghuysen, a longtime philanthropist whose endeavors included the donation of land for the Morris County Library, took steps to ensure Whippany Farms would become an arboretum after her own death. In 1971, the Frelinghuysen Arboretum was established with most of the estate’s buildings and layout left intact. Just six years later, Whippany Farms was added to the National Register of Historic Places.
