We were in Chartres for a too-short drive-by this past December. It was my fourth visit. The French Romanesque and early Gothic styles have real appeal for me.
I am noodling the possibility of a similar youth pilgrimage in this neck of the woods. Except that we don’t have a world-famous cathedral and a relic of the Mother of God.
My knowledge of your area is pretty slim, but aren't there martyrs' shrines or relics nearby?
If you like gothic architecture, you must visit the cathedral near me the next time you're in this neck of the woods. It's neighbor cathedral in NYC gets a lot of the attention, but it is IMHO the more beautiful of the two.
