Mishnayos Menachos Perek 11 Mishnah 2

In the case of both the two loaves and the shewbread, the kneading of their dough and the forming of their loaves take place outside the Temple courtyard, but their baking takes place inside the Temple courtyard. And their preparation does not override Shabbat. Rabbi Yehuda says: All of the procedures involved in their preparation take place inside the courtyard. Rabbi Shimon says: One should always be accustomed to say that the two loaves and the shewbread are fit if they were prepared in the Temple courtyard and they are also fit if they were prepared in Beit Pagei, outside the Temple Mount, as he maintains that they may be baked outside the Temple courtyard.
