Hohlenstein-Stadel is a cave located in the Hohlenstein cliff (not to be confused with the Hohle Fels) at the southern rim of the Lonetal (valley of the Lone) in the Swabian Jura in Germany. While first excavations were started after the second half of the 19th century, the significance of some of the findings was not realized until 1969. The most significant finding was a small ivory statue called the Löwenmensch, which is one of the oldest pieces of figurative art ever found.
