Aside from the first and second Temples in Jerusalem, the only other Jewish Temples where sacrifices were brought were built by Jewish priests in Egypt.
The Mishna on today’s daf teaches that someone who pledged to bring a sacrifice must bring it in the Temple in Jerusalem, and not in Beit Honyo – the Temple of Onias. Even if the person specifically committed to bringing the sacrifice there he cannot do so, rather he must bring it in Jerusalem.
The Gemara quotes a baraita that brings two opinions about the Temple of Onias. According to Rabbi Meir, that temple was a place of pagan idol worship; Rabbi Yehuda rules that only Jewish sacrifices to God were brought there.
According to Josephus, the Temple of Onias was built in Leontopolis in Egypt by the son of the High Priest Onias III, sometime around the year 155 BCE. This temple was modeled after the Temple in Jerusalem.
At Leontopolis, in the wake of the Seleucid persecution, the exiled Zadokite priest Onias founded a functioning sacrificial sanctuary that operated until the Roman closure.
