Final answer:
Herod renovated the Temple in Jerusalem during the 1st century BCE, making significant modifications and transforming it into a monumental structure.
Step-by-step explanation:
Herod renovated the Temple in Jerusalem during the 1st century BCE. He made significant modifications to the Temple complex, including adding two concentric walls to enclose the precinct and building two monumental gates on the western and eastern ends. The Temple itself had a rectangular footprint and included a cella for the worship of Jupiter-Hadad.
Herod's renovations transformed the Temple into a truly monumental structure, incorporating elements from different architectural traditions, such as the Italic and Hellenistic styles. The Temple represented both the changing realities and the cultural landscape of the Mediterranean world at that time.
