Every Christmas at my house we make ersatz "gingerbread" houses from graham crackers and icing. Since normal houses got boring about the time I was in the 9th grade, I started making gingerbread houses in the shapes of famous archetecture and recognizable monuments. To date I've replicated the Eiffel Tower, Wright's Fallingwater House, and a bowling alley. This year, to commemmorate my sister's upcoming trip to Italy I built the Gingerbread Colosseum. This is a picture I took when I was done. If you look down in the middle you can see my attempt to suggest the hypogeum of the real thing.
