We all know that the Western Wall, the Kotel,is the last remnant of our Temple.
We also know that Jews from around the world gather here to pray. People write notes to G-d and place them between the ancient stones of the Wall.

He hired many workers who toiled to make the Temple more magnificent and to widen the area of the Temple Mount by flattening the mountain peak and building four support walls around it.
