Does that basilica exist today? Is it St. Paul-Outside-the-Wall? With the chains? That was so moving.

Does that basilica exist today?

Yes .. it is still there and a popular destination of pilgrims to Rome.

With the chains?

The chain that, according to the most ancient tradition, attached the Apostle Paul to the Roman soldier assigned to guard him while in prison in Rome, is the most precious among the relics and objects on display in this chapel. Already in the 5th century, Pope Leo the Great made mention of it.
