The Hillside Avenue Historic District runs 27 acres between Watchung and Martine, holding some of the finest turn-of-the-century architecture in Union County. We are the neighbors who look after it.
Thirty-eight contributing houses line Hillside Avenue and its neighbors, most built between 1900 and 1925. Take a visual walk through the district below, then explore the complete directory of every home — with dates and descriptions from the 1982 National Register nomination.
