One of the finest houses in New Haven is this stately residence, the Aaron Skinner Mansion on Hillhouse Avenue. The mansion was built in 1832 for Aaron Nichols Skinner (1800-1858) from plans by architect Alexander Jackson Davis. Skinner was a Mayor of New Haven (1850-1854), and for a short time, ran a boys boarding school out of this house. Skinner was also a CT State Representative, serving two terms. The house was originally built as a three-bay, two-story house with one-story side wings and a rear ell. After his death, the house was purchased by Judge William W. Boardman, who in 1859, modernized the property hiring architect, Henry Austin, who filled in the side wings and added Italianate window mouldings. The monumental portico supported by fluted, Ionic columns, creates such a stately presence for the early house on the street. In the early 20th century, the mansion was owned by Rutherford Trowbridge, who renovated the house for his own use. The house remained in the Trowbridge family until the death of his last daughter, Miss C. Rachel Trowbridge, when the estate became the property of Yale University.
