Although the word "Capitolium" (pl. "Capitolia") could be used to refer to any temple dedicated to the Capitoline Triad, it referred especially to the temple on the Capitoline Hill in Rome known as "aedes Iovis Optimi Maximi Capitolini" ("Temple of Jupiter Best and Greatest on the Capitoline"). The temple was built under the reign of Lucius Tarquinius Superbus, the last King of Rome prior to the establishment of the Roman Republic. Although the temple was shared by Jupiter, Juno and Minerva, each deity had a separate "cella", with Juno Regina on the left, Minerva on the right, and Jupiter Optimus Maximus in the middle. It included a podium and a tetrastyle (four column) pronaos (porch).
