I have twice stayed in Chartres. I loved it for the cathedral which has a massive labyrinth inlaid in the floor. Then I came back here to the Napa Valley and discovered one of our local churches has a labyrinth modeled on the one in Chartres cathedral. I like these labyrinths because walking them is a metaphor for the journey we travel through life. It's a metaphysical journey. Be sure you make a trip to Chartres to walk its labyrinth.
