Sandals Found in Spanish Bat Cave are Europe’s Oldest Footwear, Archaeologists say

In the depths of Spain’s Cueva de los Murciélagos, also known as the “cave of bats,” lies a remarkable archaeological discovery that has rewritten the history of European footwear. A trove of woven grass sandals, believed to be approximately 6,200 years old, has been unveiled, making them the oldest known shoes in Europe. This revelation has captivated the world and shed new light on the lifestyles of early human societies. Let’s embark on a journey to uncover the fascinating story behind these ancient sandals.

A Chance Discovery

The narrative of these ancient shoes begins in 1857 when miners, while toiling deep within the cave, stumbled upon an astonishing chamber. This forgotten vault contained a treasure trove of historical artifacts, including mummified remains, intricately woven baskets, wooden tools, and, of course, the woven grass sandals. These sandals, initially collected by Spanish archaeologist Manuel de Góngora y Martínez in 1867, were donated to museums, and their significance would become clearer with time.

Unearthing Ancient Soles

A recent study published in the journal Science Advances has illuminated the true age and importance of these sandals. They represent “the earliest and widest-ranging assemblage of prehistoric footwear, both in the Iberian Peninsula and in Europe, unparalleled at other latitudes.” The discovery has sent shockwaves through the archaeological community, rewriting the history books on early European civilizations.

Craftsmanship and Purpose

These sandals, crafted from grasses and natural fibers, owe their remarkable preservation to the cave’s dry and cool environment. Researchers have identified two distinct types of sandals among the collection: one with a consistent woven sole and another with a hard central core. The latter featured rudimentary laces made of fibers, suggesting a unique method of fastening—possibly between the first and second toes—with a braid that could be secured around the ankle.

Based on the notes left by Góngora, it is believed that the cave’s occupants were buried wearing these sandals. Some of the footwear exhibits minimal signs of wear, leading experts to speculate that they were specially crafted for burial purposes, highlighting the significance of footwear in ancient rituals.

Objects discovered within Cueva de los Murciélagos

Beyond the sandals, the researchers also examined other objects discovered within Cueva de los Murciélagos. Woven baskets found within the cave offer a fresh perspective on pre-agricultural societies in Europe. The intricate craftsmanship and technological complexity of these artifacts challenge previously held assumptions about early human communities in southern Europe.

Weaving a Tapestry of Tradition

The discovery not only unveils a profound piece of history but also sheds light on the enduring tradition of weaving in Europe. Today, people in Spain and Portugal continue to weave grass objects, highlighting the resilience and continuity of ancient techniques. This revelation means that the use of esparto grass dates back at least 9,500 years, showcasing the remarkable endurance of traditions that have spanned millennia.

As we marvel at these ancient sandals, we are reminded of the rich tapestry of human history, where threads of tradition are woven into the fabric of time, connecting us with our distant ancestors.


The discovery of the 6,200-year-old woven grass sandals in Spain’s Cueva de los Murciélagos has unveiled a captivating chapter in the history of European footwear. These ancient shoes provide valuable insights into the lives and traditions of early human societies, challenging our preconceptions and highlighting the enduring legacy of craftsmanship. As we celebrate this remarkable find, we are reminded of the deep roots of tradition that continue to shape our world.
