Occupied by man since the beginning of the Middle Palaeolithic Age until the Metal Ages, the Serinyà Prehistoric Cave Park consists of several shelters or caves (the Arbreda, the Mollet and the Reclau Viver).

Studies carried out have shown that this is one of the best sites in Western Europe for discovering the progression of Neanderthal man to modern man. About 200,000 years ago (Middle Paleolithic) it was inhabited by the pre-Neanderthals (Homo heidelbergensis); later (between 90,000 and 39,000 years ago) the Neanderthals lived there and finally, during the Upper Paleolithic, the caves provided a refuge for modern man (Homo sapiens). All of them inhabited this place during the last glacial periods, when the landscape was very different to that of today.

The most important discoveries include a skull found in 1973, which is the oldest remains of modern human in Catalonia (22,300 years old).

The first archaeological excavations were started by Pere Alsius i Torrent in the second half of the 19th century. In the 20th century, they were continued by Dr. Josep Maria Corominas (1943) and today, work is being carried out by researchers from the University of Girona and the Archaeological Museum of Catalonia-Girona. In 1996, the County Council of Pla de l'Estany started on the construction of the current Park.
