Look down and on the base, just above the drum, you'll see that Baccio d'Agnolo began adding a balcony in 1507 and how one of the eight sides was unfinished. There's a story behind this balcony, your guide will reveal it to you on your way as to why the work was immediately halted, and as to why to this day the other seven sides remain rough brick.
