In 1970 the altar of St. Mary’s, which had been attached to the rear wall of the sanctuary, was moved forward just enough for the priest to walk around it. Then in 1984 it was moved to the center of the sanctuary, but the tabernacle was removed from the center. Finally, in 2002, the tabernacle was returned to the central axis of the church on a newly fashioned reredos, thus leaving a free-standing altar at which it is possible to offer Mass either versus populum or ad Deum.
