Francesco Queirolo's statue "Il Disinganno" (1757; no literal translation) in Cappella Sansevero in Naples; the net covering the figure is actually 3-dimensional and a part of the marble statue itself (utterly amazing).
Giuseppe Sanmartino's statue "Il Cristo Velato" (1753; The Veiled Christ) in Cappella Sansevero in Naples; the life-like appearance of the sculpted veil covering the body is almost eerie in its realism.
Inside the amazing Blue Grotto. That pinpoint of light is the entrance to the Blue Grotto (you have to lie on the bottom of the row boat in order to clear the low cave opening).
