Kleine Feldhofer Grotte was a karstic limestone cave and a paleoanthropologic site in the Neander Valley in western Germany.

Miners uncovered a skull cap and a number of skeletal bones to be labeled Neanderthal.

[1][2][3] The cave was destroyed during the 19th century as a result of industrial-scale limestone quarrying which widened the gorge.

In 1997 a successful search for the site of the cave and its deposits yielded 24 fragments of human bone, one of which, identified as NN 13, fit exactly onto the left lateral femoral condyle of the Neanderthal 1 fossil.

In recent years a 25 meter tower has been built to take visitors from the floor of the quarried-out valley to the height of the original cave, and a reconstruction of the Neanderthal bones placed at the top.
