Ascension Cemetery is located in Rockland County, New York, on the west side of Saddle River Road, just north of the New York/New Jersey border in Airmont. The cemetery was established in 1966 by the Trustees of St. Patrick’s Cathedral in response to the increasing number of Catholic families moving from New York City to the outlying counties. Using 200 acres of woodlands acquired in 1960, an initial 35 acres were developed in time for a solemn blessing in June 1967.
