Edit: the Society of Saint Pius X has celebrated Mass at the modernist St. Pius X, at the Lourdes Shrine in France. It's a crowning even in the pilgrimage whose motto is, "To Our Lady in the Footsteps of St. Pius X." Despite the large size of the church meant to accommodate throngs of pilgrims, it looks practically full. The building can accomodate 25,000 worshipers. The celebrant for this Christ the King Mass was Bishop Fellay with Bishops de Galaretta and Tisser de Mallerais in attendance, is part of a celebration for the centenary of St. Pius X.
Amazingly, they got permission to do this from the authority in charge of the site which must have been high level indeed. This is a signal event.
