Check out this Roman Coliseum constructed out of gingerbread. The architect is attending baking school, and one of the projects was to make a gingerbread structure on the theme of "Famous Buildings." It took three days to build.
How great would this thing be with some tiny edible gladiators, and tiny edible lions, and perhaps a river of raspberry or strawberry blood flowing through it? The Roman Coliseum was famous for its reenactments of famous battles, animal hunts, and executions.
