Oratory dedicated to Our Lady of Montserrat where we can see a small image with offerings of rosemary. It is located about 60 meters below the hermitage of Sant Salvador. It is usually open on the same days as the hermitage of Sant Salvador.

The Grott Mine is a tunnel of almost one and a half kilometers that is located in the Sierra de Collserola. Its construction was to carry water from the Pantano de Vallvidrera to the old municipality of Sarrià.

A strange cave in the side of the trail. It is a popular place for people to visit on a nice trail near Can Coll. I am not sure if the cave actually goes anywhere but the trail at the right time of the day gets beams of light that are magical.

According to Sergi Falguera, a collaborator of the Friends of the Geology Museum association, the site began to be exploited in the 17th century, but the most important extractions date back to the 19th and 20th centuries, when it was named Juanita. . It was part of the land of the Masia de Santa Caterina, in the neighborhood of Pedralbes. The mine still has several access tunnels. It is low in water, but it is not drinkable because it carries the acid that is formed from the oxide of minerals
