Here’s an interesting essay:
The period following the Maccabean Revolt ushered in tremendous expansion in the city of Jerusalem and even on the Har Habayit (Temple Mount).

As a result, Jerusalem in this period once again became a prosperous and beautiful city. But to understand these important developments, it is necessary first to know what happened in the aftermath of the re-conquest of the city and Beit Hamikdash (Holy Temple) under Yehudah (Judah) the Maccabee in the revolt of 168-164 BCE.
