I think what is being referred to in the discussion is the former Ottoman Islamic court bu idling which is at the end of the Street of Chain. It's southern wall is what one sees when standing at the Kotel and you look up to your left. It's eastern portion actually is located inside Har Habayit albeit one floor up, being supported by the columns alongside the western wall of the mount inside. There is where Rav Goren's synagogue is located, containing an Aron Kodesh and Sefer, by the way. It serves the Border Police, well, those that are Jewish and we daven there on Tisha B'Av Mincha and also Mincha of Yom Kippur. Technically, it is "inside" but one cannot step onto the platform in the physically sense.
