Crocker-McMillin Mansion, Gothic Revival mansion in Mahwah, US.
The Crocker-McMillin Mansion is a Gothic Revival residence in Mahwah, built by George Crocker, son of a railroad magnate, between 1903 and 1907. The building draws architectural inspiration from Bramshill House in England, featuring expansive halls and multiple levels throughout its structure.
George Crocker built the mansion between 1903 and 1907 on the former Darling estate as his private residence. In 1927, it was converted into a seminary for religious training and served that purpose for nearly 60 years.
The mansion served as the Immaculate Conception Seminary from 1927 to 1984, transforming it into a center for religious education and training. The grand rooms were repurposed for study and prayer, giving the building a second life with spiritual purpose.
The property spans approximately 12 acres with outbuildings such as greenhouses and stables that reflect its original purpose as an estate. Plan to spend time exploring both the main building and the grounds to understand the full scope of the site.
The mansion was known for its productive vegetable gardens, whose harvest was sold in New York City markets, showing the family's connection to commerce networks. This agricultural operation was unusual for a residence of such size and prestige.
