What structure was the intended location for michelangelo's david

Originally commissioned by the Opera del Duomo for the Cathedral of Florence, it was meant to be one of a series of large statues to be positioned in the niches of the cathedral's tribunes, way up at about 80mt from the ground. David was originally commissioned as one of a series of statues of prophets to be positioned along the roofline of the east end of Florence Cathedral, but was instead placed in a public square, outside the Palazzo Vecchio, the seat of civic government in Florence, in the Piazza della Signoria, where it was unveiled on. Hope this helps!
