Jerusalem

Jerusalem, also known as Salem or Zion, is the Jewish holy city and the third holiest city in Islam. After King David conquered the city, it became the capital of the United Israelite Kingdom and later of Judea.

King Solomon build the first Jewish Temple, which I believe was destroyed when Judea was conquered by the Babylonian Empire. The Second Temple was built in the time of Ezra and Nehemiah, and expanded in the time of King Herod. The second temple was destroyed in the Great Jewish Revolt, c. 70 AD.

Jerusalem is also used in a poetic context to refer to the nation of Israel, or to the Jewish people. The end of Revelations speaks of a New Jerusalem to come.
