This is the Holy Trinity Catholic Chapel of West Point. While the altar is a bit too box like, they have made the best of a not so good liturgical choice for the altar. I see it is set up for the Modern Roman Missal Mass to be celebrated ad orientem.
The Marine base at Paris Island also celebrates Mass ad orientem. Men, especially real men, seem to like ad orientem better than the more “feminine” facing toward the congregation type Mass.
I wonder though, did these manly men at West Point decorate the chapel for Christmas. Maybe it was a way to camouflage Christmas Mass in war time outside?
