Here is a cutaway view of the central arcology of "Serenity City 3." This fity-story high, nine-sided building has industrial facilities in its three-tier base as well as underground. The outer portion of most of the structure is a tiered shell of apartments with each tier being two stories high. There are nine lower tiers and nine upper tiers separated by a sizeable gap created by nine hourglass-shaped columns. In this gap is a landscaped promenade with nine apses where cultural events are held. Supporting the entire building are eighteen thick angled ribs and nine nine-sided columns with landing pads for VTOL aircraft at their tops. The arcology is capped off with ring containing water tanks and HVAC equipment. A large opening in the center allows sunlight to get into the sizable atrium where a multi-faith house of worship sits atop a tall nine-sided platform. The platform houses governmental offices, a hospital, education and research facilities, and a market. Nine pedestrian bridges extend from the promenade to the temple. This is the final image of the "Serenity Cities" series to be posted on Renderosity.
