Use these tables for laying out an actively used temple complex. I tend to model temples after churches. There is a primary worship chamber where most prayer ceremonies are held. This chamber’s size can vary greatly—in a city, the temple might accommodate 1,000 worshipers or more at a time with room for crowds to spill out into a square in front of the temple; in a rural setting or for an obscure faith, the temple might accommodate 100 worshipers or less. Then there are adjacent rooms, wings, or other nearby buildings to support the operation of the temple. These tables are designed to work primarily with this design model in mind, but other layouts are possible.
