The Puig de l'Àliga, at 464 meters above sea level, is not the highest peak of the Garraf, that honor goes to the Puig de la Mola (534 meters), but it is the highest of the foothills southern parts of the Garraf massif. It forms a natural border between the regions of Alt Penedès and Garraf and is a natural viewpoint of both the Penedès plain and the Garraf coast. At its highest point there is a geodesic vertex, a large cross, and a fire watch tower.

Necropolis located on the elongated hill located in front of the Olerdolana wall. It is known as Pla dels Albats (relatively modern place name). This name comes from the numerous small and medium-sized tombs corresponding to infants and alabtas (babies who died before receiving the sacraments or having the use of reason) found in the necropolis of anthropomorphic tombs. More than a hundred tombs have been located. The graves are excavated in the rock, they are rectangular in plan, with the head separated from the rest of the body and narrower at the feet. Most feature a socket in the rock itself for the cap. The graves follow the east-west orientation. In the middle of the necropolis are the ruins of a building that has been identified as the remains of the chapel of Santa Maria. Part of the north wall is preserved, with a height close to 3 meters and the west wall, modernly altered. The chapel of Santa Maria and the necropolis must be associated with the population, more or less dispersed, located outside the walls in medieval times. They were already in operation at the beginning of the 10th century. Observations: Archaeological research is very incipient in this sector, its evolution will confirm the exact functionality of the building described, its chronology and the relationship with the remains of another building that can be guessed in the middle of the necropolis.

Small peak, near a quarry, where a series of rural roads converge. This is a typical area of the Penedès with extensive fields of vineyards interspersed with scattered farmhouses where you can also appreciate old quarries. From the top, if the vegetation allows us, you can see from Montserrat, la Mola, la Morella, el Montmell, el Montau and el Puig de l'Àliga, among others. As can be read on a small panel at the top, the Toponym derives from the word "popia", which in the geographical vocabulary of the popular language designates a hill of low height, with a regularly rounded shape and a wide base: the shape of the chest of 'a woman. The word "Papiol" derives from this metaphor. The name is already documented in 992 as the boundary of Viladellops (Olèrdola). Essential peak included in the list of 100 peaks of the F.E.E.C. https://www.feec.cat/activitats/100-cims/cim/penya-del-papiol/

Pla dels Albats Necropolis owes its name to the numerous tombs of children and newborns (babies who died before receiving the Sacraments). More than a hundred tombs outside the enclosure are documented. The tombs are excavated in the rock, they are rectangular with the head differentiated from the rest of the body and narrower at the feet. Most of them have a lace in the same rock for the cover. This consisted of one or several slabs that protected the body. The graves follow the east-west orientation.
