A quarry whose operation began in 1920 in the southeast foothill of Puig de Olorda was enlarged by the addition of another older quarry called Can Ferrers o Can Farras, located further north, with both quarries then included in the Sanson concession. Most parts of the quarry are within the Sant Feliu de Llobregat township, although the northern front of the open pit is within the Molins de Rei township and the east front of the open pit is within the Barcelona township.
The modern cement factory dates from 1967 until it's closure as an operational factory in early 2000s. From the quarries Silurian-Devonian limestone was extracted for the cement manufacturing and transported to the factory via giant aerial conveyor belts. The factory was owned by Cemex but was purchased by molins cementos shortly before operations ceased.

The quarries closed at the end of the 90's and are now undergoing a process of restoration to restore the landscape to parkland.
The Factory is an ABANDONED (production ceased) site and is not safe to visit inside. Access is STRICTLY PROHIBITED and the site is permanently monitored and patrolled by on site security. Police will be summoned if you try to break into the factory.
The factory can be viewed from the outside, ensuring to stay on the road and outside of the fence line, never crossing any of the marked danger signs or barriers.
The various conveyor belt systems in the mine area can also be viewed from the paths but are heavily corroded and not to be used in any form as bridges or for climbing.
The trees are mostly oak and cork with some pines so in Summer and spring there may be poisonous Pine Processionary Caterpillars.
Be sure to to stay on the path indicated in the walking route and be aware that off the path there are mine edges with sudden and high drops or risk of rock falls. Keep children and dogs closely supervised until out of the mine area at Creu de Olorda.
This is a short walking route not far from roads so I always do it with a small rucksack of the essentials. Emergency waterproof jacket is optional depending on the weather forecast.
1 - 2 litres of water because there are fountains along the route.
