A family member has just returned after spending 5 days at the International Pilgrim Center attached to the Shrine of St Philomena at Mugnano, Italy. (Details are available on the internet). This facility can house around 70 people, yet during all the days she was there, she was the only guest. When checking out however, a couple from Switzerland (also SSPX) checked in.
So many Traditional Catholics have a great devotion to St Philomena. Perhaps they haven't heard of this facility?
