The center of the Roman Empire is in Italy. ROME. And to be specific,
there was a spot in the forum called the "umbilicus urbis Romae" which
is translated "the center of the city of Rome" or "the navel of Rome".
At any rate, it was the spot from which all distances, from all over the
empire, were measured.
I’m thinking, maybe symmetrical.
I belive A,B,D, E, F, G, and I, are correct. My reasoning is; ancient Egyptians were big on beer, and their beer was made with grain, so they would have breweries, and granaries around and available.
They also had medical places to treat the injured working on the pyramids (I know that from watching a documentary.) I'm not so sure about the child care ones (they did have schools though), that you'd have to look up.
I know for certain they had housing around the pyramids, and bakeries for baking bread. And I'm 90% sure they had cemeteries around the pyramid cause I mean, they had a city there, and back in the day people were dropping like flies ;)
