After exploring every nook of the church, I nonetheless ended up with about an hour and a half to spare before Mass started. I decided to go for a walk, even though yesterday's high was 42 degrees outside, brr! I was wandering along the edge of the Catholic University campus (where the Shrine is located), when I spotted a sign that said "Pope John Paul II Cultural Center" with an arrow pointing in the direction in which I happened to be meandering. I had never even heard of the place, but I decided to follow the signs and check it out. Ha ha, I literally entered the building, walked up to the front desk, and asked the receptionist, "Where am I?" She was very helpful, if not bemused by my utter lack of knowledge.
What serendipity! The center doubles as a museum and an ecumenical and scholastic center of sorts. I loved so many things there. They had an amazing collection of crèches from around the world, ranging in size from thimbles to several feet tall. My favorite nativity was a small, adorable one from Uruguay, which struck me as quite a cozy little family:

The center had a chapel in the back of the museum, which had a kneeler in front of a crucifix where Pope Benedict XVI knelt when he visited D.C. last April! I knelt on it, and thought about what the pope might have been praying for when he was there. So cool. There was also a room that intertwined the history of Poland with the biography of Pope John Paul II, who was Polish, of course. The room meant a lot to me, in light of my own Polish descent. It also featured a collection of things that JPII used (like his red leather papal shoes), and a huge number of photographs from his international visits, which I found very moving.
I really enjoyed my adventure yesterday afternoon. I will definitely visit the Shrine again. The Mass that I attended was in crypt church, so I still want to attend a Sunday Mass, which will have more expansive music--though, I must say, the organist who played yesterday in the crypt church was quite talented. What a blessed afternoon.
