About the Retreat Center

Mariandale Retreat and Conference Center, located 35 miles north of New York City in Ossining in scenic Westchester County, is sponsored by the Dominican Sisters of Hope. Less than an hour’s drive or train ride from New York City, Mariandale is situated on 55 acres on the eastern bank of the Hudson River.

Situated at the edge of a peaceful wooded area, the Center faces west to a view of the Palisades, overlooking the valley and its beautiful sunsets. This bucolic setting is the perfect place to get away for a weekend. 

Individual rooms for overnight guests as well as ample space for small groups allow retreatants to rest, relax, and reconnect with God and others.

Mariandale’s chapel, with its African mahogany seating and circular plan, offers a quiet and prayerful space for meditation. A hammered bronze reredos with an abstract sculpture of the “Seven Gifts of the Holy Spirit” and the rich, gloriously colored, stained glass windows depicting “The Creed” provide a joyful atmosphere for the celebration of liturgy.
