The Piazzetta dei Leoncini is part of St. Mark's Square, or Piazza San Marco, in Venice.
The two tall columns represent Venice's two patron saints. Atop the column on the left, St. Theodore (Teodoro), is stepping on a crocodile. The winged lion of St. Mark the Evangelist (Marco) stands on the column to the right.
The Doge's Palace (Palazzo Ducale) behind the columns was originally constructed in the ninth century, although the current structure dates to the fourteenth and fifteenth centuries. The palace was the residence of the Doge and housed government offices.
