The Roman Forum is a plot of land outside the Coliseum that represents what's left of the 1 million people that used to live in that empire. Yeah, you heard that right they squeezed 1 million people into a very small area, and I thought Seattle rent was high. Another fun fact, the entire forum was covered for a long while due to the location of it in the city, dust covered up the entire place until someone stumbled upon the find of a lifetime.
Theme: the tan-red of buildings left behind that used to be covered in ivory.
