Two huge Celtic crosses keep silent watch over the landscape of Cochise County. One graces the Holy Trinity Monastery, a Benedictine community just south of St. David. The second is on a hillside overlooking Our Lady of the Sierras Shrine near Hereford. Both tower more than 75 feet over their surroundings, and both are the result of a journey Pat and Gerry Chouinard made to a shrine in Medjugorje, in what was then Yugoslavia. When they retired in 1995, the couple decided to build a similar shrine on their property near Hereford.
