Not far from St. Nicholas parish, Saint Anthony's Chapel on Troy Hill  houses more than 6,200 relics — the largest collection outside the papacy in Rome, and the largest worldwide that is open to the public.

Lining the sides of the chapel are large wooden statues in scenes depicting Christ's life.Relics, as you probably know, are actual pieces of saints' bodies, or sometimes their personal belongings.

Supposedly authentic and still being added to, the collection is housed in ornate casings.

The chapel, built in 1890 by a rich priest, allegedly has a splinter of the "true" cross and a thorn from the crown of thorns.

No photos were allowed in the building, and to be honest, the whole thing sort of creeped me out. But how interesting that Pittsburgh, Pennsylvania, United States is a pilgrimage site for the entire Catholic world.
