Mount Acra is located in Jerusalem on the north side of Mount Zion between the Tyropoeon Valley and the Hinnom Valley. it is interesting that Simon Maccabeus nearly filled up the Tyropoeon Valley which is located between Mount Bezetha and Mount Acra. He also reduced the height of Mount Acra in order to make it lower than Mount Moriah where the Temple stood. Antiochus Epiphanes, ruler of the Seleucid Empire built a fortress in Jerusalem on Mount Acra after he conquered the city in 168 BC. It was here that the Syrians governed the Jews. Later this fortified compound was destroyed by Simon Maccabeus. Mount Acra was important in the Maccabean Revolt and the formation of the Hasmonean Kingdom.
