The Septizodium was a building in ancient Rome. It was built in 203 AD by Emperor Septimius Severus. The origin of the name "Septizodium" is from Septisolium, from the Latin for temple of seven suns, and was probably named for the seven planetary deities or for the fact that it was originally divided into seven parts.

Now, you can have the Septizodium as your very own schematic. Credit, as usual, to theannihilator2 for teaching me how to build stuff like this.
