With the ‘Nautical Celebrations in the Port of Cagliari’ on your left, head back through the two empty rooms. From the second, take the door to your left and descend six steps to reach the landing of the same spiral staircase you took between the ground and the first floor; climb the steps on your right up to the second floor. Open the only door on your right and enter the section dedicated to Decorative Arts. In this first room, you’ll see a three-metre-long display case on your right, containing 42 ivory and bone items. Approach its left side, find the first object in the top left-hand corner and listen to the stories.
