The Fr. Suitbert G. Mollinger Museum is arguably the most overlooked of all the chapel's resources. This quaint museum houses many artifacts pertaining to Fr. Mollinger’s life as a medical doctor, pharmacist, priest, and wonderworker.
The first suggestion of a Chapel Museum came in a memo from Fr. Mueller, pastor of Most Holy Name of Jesus during the years of its restoration.
At a meeting on January 19, 1984, a motion was made to establish a museum and that work be started to get the area ready as soon as possible.
The minutes of the October 8, 1984 meeting recorded that the museum was finished and ready to have exhibits put in place.
Parishioners and others were asked to make gifts of items pertaining to the chapel and Fr. Mollinger that they had in their possession for display. Items continued to be donated, were cataloged and put on display. The museum dedication took place on June 10, 1986. The speaker was Fr. Richard S. Wersing, C.S.Sp., and Mrs. Joan Ivey of the City of Pittsburgh Historic Review Commission cut the ceremonial ribbon.
Items of religious and cultural interest housed in the museum include a number of crutches, eyeglasses, and items left by the faithful who claimed cures from their illnesses.
The Fr. Suitbert G. Mollinger Museum is open Tuesdays, Thursdays, Saturdays, and Sundays, from 1 to 4 p.m., and in conjunction with most pre-arranged group pilgrimages.
