Ear of Dionysius is so named because its cave opening resembles a cat's ear, hence it is also called the Cat's Ear Cave. The shape here is quite unique, with a wide entrance and a winding, deep interior that looks as if it were intentionally carved. Speaking inside amplifies the sound significantly, acting as an amplifier.

Show More ReviewsIt is a cave with an entrance shaped like a cat's ear, commonly known as the "Cat's Ear Cave". The Syracuse people dug it according to the acoustic principle. Anyone speaking in the center of the cave will become a soprano or a soprano, and the sound will be amplified dozens of times. Dionysius was a tyrant in Syracuse. It is said that the tyrant used this acoustic effect to eavesdrop on the prisoners' conversations.
