Crocker-McMillin Mansion

The 75-room, three-story Crocker McMillin Mansion , was built between 1901 and 1907 on the Darlington estate for George Crocker. After Crocker died in 1909, the banker Emerson McMillin lived in the estate until his death in 1922. From 1927 until 1984 the mansion was occupied by the Crocker-McMillin Mansion-Immaculate Conception Seminary. The estate, located at Crocker Mansion Drive in Mahwah, New Jersey, is one of New Jersey's historical landmarks and listed on the National Register of Historic Places in 1997.
The Darling estate, over 1,100 acres, was purchased by A. B. Darling in 1872. The Darlings placed a mansion on the property, as well as a racetrack for horses. The Crocker-McMillin Mansion is located on the former Alfred B. Darling property, which was purchased by the Crocker family of New York City in November 1901. George Crocker described the property as "the finest site for a residence in the country." In response to rumors of the possible purchase, the Ramsey Journal wrote that "the coming of such a man would mean much to our town." He brought horses to the estate. Early in 1902, Crocker acquired the well-known racehorse King Muscovite, and by September 1902, his horses were winning awards. Crocker had 4,000 trout brought for the property's pond in the spring of 1903 from Plymouth, Massachusetts, and bass were also added. By the spring of 1904, the old Darling racetrack was again usable for exercising Crocker's horses.
