Did Cyrus build the second temple in Gaza?

No, Cyrus the Great did not build the Second Temple in Gaza. The Second Temple, which was constructed after the Babylonian Exile, was built in Jerusalem by the Jewish people, with significant efforts led by figures like Zerubbabel and later completed and expanded by King Herod. Cyrus is known for issuing the decree that allowed the Jewish exiles to return to Jerusalem and rebuild their temple, but he was not directly involved in its construction.
