The prehistoric site itself is located in a collapsed cave, nestled in a sandstone bluff overlooking the Krapinica River in Hrvatsko Zagorje.

Called the Heritage Museum of Krapina, it showcased the total history of the area, beginning with select prehistoric Neanderthal finds, and up to the Yugoslav Partisans.

As the adaptation and renovation of already existing structures appeared to be more expensive than building a new one, the idea of making a new one from the ground up was accepted.

The entrance to the building opens up into a large oval atrium of grey concrete, the opposite of which is a broad screen which continuously plays documentary films on Krapina Neanderthals.

The passage up to the second floor is of a circular shape, with museum pieces being placed in the open space, as well as along the painted walls.

[6] 1191 lithic artifacts were discovered during the century of research at the site, and were found in all ten geologic levels as defined by Gorjanović-Kramberger.

[1] According to the Middle Paleolithic typology set out by François Bordes, the Krapina lithic assemblage can be categorized as Mousterian, with a mix of various tool classes.

The assemblage is dominated by side-scrapers, comprising more than half of all stone tool finds, which would classify it as Charentian Mousterian.

He based this assumption on three factors: mixing of animals and human skeletal remains, breaking of long bones (in order to access the marrow), and the fact that not a single skull was found in a non-broken state.

[8][9] Some scientists believe around 80 individuals are represented, and that the fossils found here were accumulated in a relatively short period of time 130 thousand years BP.

[20] Krapina's Neanderthal remains represent the largest and most complete hominid collection known, with almost all parts of the human skeleton being found at the site.

Based on reconstruction of the fragmented remains through 3D modeling, an average cranial capacity was set between 1326–1359 cm3,[19] which is slightly larger than among anatomically modern humans.

As such, the Krapina sample, taken in conjunction with first cervical vertebra found at Sidrón Cave, seems to confirm such anatomical variation in Neanderthals.

[26] Some Neanderthal anterior teeth show traces of unusual and excessive gross wear, which is usually indicative of non-dietary tooth use.

The most common explanation for such tooth wear is the "stuff and cut" scenario, according to which teeth are used as a "third hand" for grasping materials that required additional processing with tools.

All four of these teeth show various traces of grooving and enamel scratching, which implies that the Neanderthal attempted to alleviate tooth pain through a direct, mechanical approach.
