The Prado de las Cruces Dolmen, located in Bernuy-Salinero, is a unique example of megalithic architecture.

The funerary monument corresponds to the type known as "corridor tombs", consisting of a circular chamber and access corridor, oriented to the southeast, all covered by a mound of earth and stones, which in the space preserved reaches 20 metres in diameter.

It was used as a burial site from the late Neolithic to the early Bronze Age, between the last centuries of the 4th millennium BC and the first third of the 2nd millennium BC.
