Archaeological investigations in Spain and France have identified subterranean cave systems utilized by Neolithic and prehistoric populations for ritualistic, funerary, and industrial purposes.

在西班牙與法國的考古調查中，發現了新石器時代及史前人群用於祭祀、葬禮及工業用途的地下洞穴系統。

The utilization of deep cave networks, such as the Cueva de los Murciélagos in Andalusia, indicates a pattern of high-risk penetration into hypoxic and unstable environments. Evidence suggests these sites functioned not as residential dwellings but as loci for complex funerary practices and symbolic behaviors. The presence of human remains in isolated chambers, alongside perishable artifacts like woven baskets and leather footwear dating back approximately 9,500 years, supports the hypothesis that these spaces served as portals for ritualistic rebirth or death. The occurrence of solitary skeletons suggests fatalities resulting from geological collapse or asphyxiation, although the possibility of ritual sacrifice remains a subject of academic inquiry.

對深層洞穴網絡的利用（例如安達魯西亞的 Cueva de los Murciélagos），顯示出一种進入缺氧且不穩定環境的高風險模式。證據顯示這些地點並非作為居住房屋，而是複雜葬禮習俗與象徵行為的場所。在獨立密室中發現的人類遺骸，以及約 9,500 年前可腐壞的文物（如編織籃和皮革鞋），支持了這些空間作為祭祀重生或死亡之門的假設。單獨骨骸的出現顯示可能是地質崩塌或窒息導致的死亡，儘管祭祀獻祭的可能性仍是學術探究的課題。

Parallel to these ritualistic sites, recent excavations in the Spanish Pyrenees at an elevation of 7,333 feet have revealed evidence of prolonged human occupation. The discovery of approximately 200 green mineral fragments, tentatively identified as malachite, suggests an early engagement with metallurgy. The coexistence of thermally altered and unaltered minerals, adjacent to combustion pits, indicates a purposeful attempt to extract copper through heat application. This technological activity was contemporaneous with the deposition of symbolic artifacts, including bear-tooth and shell pendants, implying that high-altitude sites functioned as multifunctional hubs for both industrial experimentation and social signaling.

與這些祭祀地點平行，近期在海拔 7,333 英尺的西班牙比利牛山脈挖掘中，發現了人類長期居住的證據。發現約 200 塊綠色礦物碎片（初步鑑定為孔雀石），顯示了早期對冶金的接觸。在燃燒坑附近同時存在受熱改變與未改變的礦物，顯示其有意嘗試透過加熱來提取銅。這種技術活動與放置象徵性文物（包括熊牙和貝殼吊墜）同時發生，暗示高海拔地點是工業實驗與社會信號傳遞的多功能樞紐。

Current evidence suggests that prehistoric subterranean sites in Southern Europe served as critical centers for spiritual practice and early technological development.

目前的證據顯示，南歐的史前地下遺址曾是靈性修行與早期技術發展的關鍵中心。
