Tonight on 60 Minutes Presents, Preserving the Past.

The $540 million National Museum of African American History and Culture is rising on the national mall.

Its complexion rendered in shades of bronze, a building of color against history's white marble.

This is not the museum of tragedy. It is not the museum of difficult moments.

It is the museum that says, here is a balanced history of America that allows us to cry and smile.

Italy is home to two-thirds of the world's cultural treasures.

Trouble is, the country's too broke to keep its historic ruins, churches, and monuments

from crumbling to dust. But now some of its most treasured

and endangered landmarks are being saved, not by the government, but by a more respected

Italian institution. The fashion business. There is a very famous Kennedy speech, no?

What is possible for us to do for our country?

We need to do now.

When Pope Benedict the 16th came to the Sagrada Familiar,

he consecrated the church as a basilica.

Not since 1883, when it was first envisioned by Anthony Gowdy, had it been seen in all its glory.

He wanted to write the history of the whole of the Catholic faith in one building.

I mean, how crazy and how extraordinary and how ambitious that idea is.
