You can create temple designs now. There is a paper in the museum that will help you create the temple designs. If you don't have this paper, here is some help as to where to find it:
Temples of Ancient Greece: Go to the right and to the middle display. See a temple reproduction and a "Create your own temple" stand. Pull back and turn around. Take the Temple Architecture paper from the bench at left.
Complete this task for Melina.
