The Shrine itself is neat enough, but find the basement. That's where the cool crypt chapel is and the last papal crown.
I intend to go there on Sunday. However, the Basilica certainly doesn't have the last papal crown in existence; I've seen three other ones before. Maybe you meant the one last used by Paul VI?
Usually, dignataries are met at the White House. You didn't arrange a state visit, your highness?
It was a spontaneous trip, otherwise I would've definitely figured out a way to get into the Presidential Palace (as well as a tour of the Pentagon).
So what's your itinerary for our fair city? Anything cool?
My plan so far for tomorrow (Saturday) is to visit
Anderson House, the
Frederick Douglass National Historic Site, the
Washington National Cathedral, and the
National Gallery of Art. Dinner will be at an establishment called the
Napoleon Bistro.
On Sunday, I'll visit the National Shrine, Franciscan Monastery, and St. Matthew Cathedral.
