We will find this curious monument in San Martín de Montalbán, just over a quarter of an hour by car from the Casa Rural “Finca los Pájaros”.
It is a Neolithic funerary building from the Bronze Age, which houses a circular crypt, made up of several menhirs located vertically, and which form the base of another in a horizontal position.
In addition to getting to know this interesting monument, there are innumerable options for different hiking routes in the area.
