The Dupnisa Cave (Turkish: Dupnisa Mağarası), aka Dupnisa Caves, is a show cave located in Kırklareli Province, northwestern Turkey, close to Bulgarian-Turkish border. The cave itself, unlike what the original name suggests, is actually three, interconnected caves divided into two separate floors. Its name is derived from the Bulgarian word Dupnitsa (Дупница), related to the word for "hole".
