What you might not do is walk up and into the chapel, and even if you do you might not notice the small white marker tiles set into the floor. One marks where her heart lies (in front of the altar), one her vestments, one her crucifix; I don't know if they are still there.
Catherine's head, and one finger, are preserved in a reliquary in her chapel proper, which lies further down the church on the southern side of the church. The rest of her is buried in Rome.
I only noticed the marker tiles by accident, but thought I should share. Apologies for the quality of the photos; I have dreadful camera-shake sometimes!
