Moinhos Velhos Cave, Natural cave system in Mira de Aire, Portugal.
The Moinhos Velhos Cave extends for 9 kilometers through limestone formations, featuring two main fossil conduits and numerous dendritic tributaries throughout its passages.
Manuel da Troucha, a local shepherd, discovered the cave in 1925, leading to its first formal exploration by Francisco Abreu in 1946.
The cave system contains valuable archaeological evidence and geological formations that contribute to understanding the natural processes of the Estremadura Limestone Massif.
Visitors can access the cave through guided tours, which include explanations about the geological formations and the cave's extensive network of passages.
The cave houses specific cave-dwelling species, including the ground-beetle Trechus lunai and the cave spider Nesticus lusitanicus.
