If you're standing on the bridge take advantage of it to look at the powerful, fortified body of the Castle and Julius II's Loggia, which you can recognize for its exquisite and elegant marble columns. It was built in the early 1500s and replaced an ancient, uncovered balcony that faced the Tiber. Below it you can see a gigantic coat of arms that reminds you of the completion of the works commissioned by Alexander VI.
