Near Santa Maria delle Grazie is the "Needle, Thread and Knot" monument. It is a tribute to Milan…read morebeing the fashion capital of the world. It is a gigantic 1 meter wide and 18 meter high steel needle (picture a five-story building) with an 80 meter colored fiberglass thread that ducks under the street & knots on the other side. It was created in 2000 by Swedish sculptor, Claes Oldenburg, and his wife, Coosje van Bruggen. I'll be honest, I didn't quite get what it was at first, but it's really cool to see. For practical reasons, its a great landmark to use while navigating around Milan. It's located in Cadorna Square, right at the Codorna station which has an express train to the airport. The best part for us is that it's right inbetween Santa Maria delle Grazie (where you see the Lord's Supper) and the Castello Sforzesco.
