The Clinton Hill Historic District was listed on the National Register of Historic Places in 1985. The district includes the mansions of Clinton Avenue, built in the 1870s and 1880s. The most prominent of these are linked to Charles Pratt, who built a mansion for himself at 232 Clinton Avenue in 1874, the year his Charles Pratt & Company was acquired by Standard Oil, and one each as wedding presents for three of his four sons. These four mansions can be seen on Clinton Avenue between DeKalb and Willoughby. The rest of the historic district is noted for its prominent Italianate and Beaux-Arts rowhouses. The Clinton Hill South Historic District was listed in 1986.
