The Van Vleck Estate is one of the largest parcels of land within the Mountain Historic District and features formal gardens and plantings. Three generations of the Van Vleck family lived on the estate and each left their imprint on the architecture and grounds. Joseph Van Vleck designed and built the current Italianate house in 1916. Beyond the limits of the estate, his architect son, Howard Van Vleck, designed several additional homes within the district. He later pursued his interest in horticulture, changing and creating the gardens on the site and developing hybridized rhododendrons, many of which survive today.  

The 2023 Trust grant will help fund the preparation of a Preservation Plan.
