The Cau dels Emboscats is one of the cavities that served as a refuge during the civil war. Specifically, several people hid from Sant Llorenç Savall. The situation of the cave was kept secret for many years after the end of the conflict. It wasn't until October 28, 1956, that Biel Dalmau, from the Mas de les Oliveres, explained its location and history to Josep Maria Torras Homet. The mouth is very irregular. It opens in the form of a chasm that falls on an inclined floor. Then there is a 2 meter ledge leading to the main gallery parallel to the cliff and about 20 meters long. In the middle of the gallery there is a large window that forms a kind of side room poured into the steeply sloping cliff. The cavity ends in an elbow and a small room, where small stalactite formations and parietal crusts can be observed.

The Sescorts caves, also called Les Corts and Los Estables, are located below the Morral del Drac, on the path that goes from the Estenalles pass to La Mola. The caves are close to the Coma de l'Abella cliff, at the foot of the Petanta Rock. They were used a few years ago to keep cattle and we can still find the roof quite smoky from the fire on the ground that they made. There are 7 small cavities with an approximate length of 25 meters. From inside there are views of the monastery of Sant Llorenç del Munt, at the top of the summit of La Mola.

The hermitage of Santa Agnès is a chapel built under the rock, near the monastery of Sant Llorenç del Munt, of which it depended. It is located in the cave that bears his name. It is documented since the 14th century and was worshiped until the end of the 18th century. It is one of the architectural vestiges in Sant Llorenç del Munt park that remain today. It is in the Santa Agnès channel on the north side of La Mola, approximately 900 meters above sea level. Traditionally it has been said that it belonged to a convent of religious women although little is known about the congregation to which they belonged. As a point of interest we find sinks inside the cave that have been used as a fountain and cistern until today, attached to the same balma where the chapel is located. This church was built in the medieval period in the Gothic style, in the form of a small rectangular nave with a pointed vault, reinforced with two lateral arches. The part of the head pours into the living rock, leaving an excavated space where there was once an altar. The existence of the hermitage has been documented since the 14th century and it is known that ceremonies were held until the 18th century.
