This is Piranesi's design for the central stele in the piazza outside the gates of Santa Maria del Priorato. The trophies signify the military prowess of the Knights of Malta, while the tower at center is taken from the coat of arms of Giambattista Rezzonico, Prior of the Knights and Piranesi's patron in the work.
