Looking at the façade of Palazzo Madama, you will see three large entrance doors in front of you. To enter the building, head through the middle door. Once inside, turn left, cross the cloakroom, turn left again and you will find yourself at the ticket office. With the ticket office on your left, go straight ahead and enter the first room on your left. You will see two exhibits along the left-hand wall. Find a good place to view the second exhibit, called the Antwerp Altarpiece, which is the furthest from you along the wall.
