River Grove is most notable for its open spaces which make up about fifty percent of the community along the Des Plaines River. Named for the Majestic Ash tree grove that once stood there, the community was home to Cook County’s second oldest Ash Tree (approximately 240 years old) until if fell victim to the Emerald Ash Borer. Today, River Grove is Home to Triton College and it’s Cernan Earth and Space Center. The Historical House and Barn in River Grove is an ongoing project of the River Grove Historical Commission. Nearly fully restored, the home will serve as a museum for the history of the village. The annual River Front Fest is a highlight each year.
