Facing the San Marco basilica, the courtyard of the Doge's Palace is a grand space offering even grander views. Two mid-16th-century well heads feature in the middle of the courtyard. Since 1567, the Giant's Staircase is guarded on either side by Sansovino's colossal statues of Mars and Neptune, representing Venice's power by sea and land. Leading to the upper floors from the Gold Staircase, you'll walk past two important plaques: one from 1362 that has Gothic lettering from the papacy of Urban V, the other stands at the Giants' Staircase and celebrates French King Henri III's visit to Venice in 1574.
