Wallkill is also a destination for international visitors to Watchtower Farms, which draws tens of thousands each year to a free guided tour of its printery. The Watchtower Society (a legal entity of Jehovah's Witnesses) has operated the facility since 1963, initially to produce food cost-effectively for volunteer workers at its offices and printeries in Brooklyn, New York. Some printing of Awake! and The Watchtower began at Wallkill in 1973, and by 2004 their entire United States printing operation was shifted from Brooklyn to an expanded Wallkill printery. The Watchtower printery at Wallkill is considered an example in automated printing, binding, and packaging. Aside from those run for the federal government, Watchtower's Wallkill plant is the largest in-plant printing operation in the United States.
