What was the Temple of Jupiter Optimus Maximus?

I have read several articles on the significance of the Temple of Jupiter Optimus Maximus which stood from the years 509 B.C. - A.D. 392. This Rome based monument was particularly useful to Roman authorities. It was a place where Roman politicians would worship Roman gods and offer sacrifices to a cult statue of Jupiter, it was a political conference center, and likewise, a fellowshipping hall for Roman politicians. It also served as a public records archive, and it also served as the endpoint for Roman triumph processions. The Temple, being the centerpiece of Area Capitolina, a precinct where certain assemblies met, and it was an important religious, political, and cultural symbol that was rebuilt four times, this being a true testament to the temple's importance to Rome's cultural identity.
