Casla is located on the slopes of the Sierra de Guadarrama, at the foot of Somosierra. The Cañada Real Soriana Occidental runs through its municipal area, a legacy of its transhumant past.
In all its surroundings we find extensive forests of oaks and junipers, as well as a beautiful limestone gorge formed by the Caslilla river, which rises next to the town. Next to the source of this river we can find a small recreational area.
What to see
Church of San Pedro Apóstol
It is located in the center of town, and on the outside it is a large building with austere lines. With a majestic plan and built in three naves, its orientation, with the presbytery to the north, is very unusual in the province. Its interior is wide and spacious. It is made up of three large bodies joined together. It has two entrances: a lintel door on the east wall and a doorway on the south wall, which is climbed by a staircase.
In the lateral naves, the baroque altarpiece of the Virgen del Rosario stands out, another dedicated to Saint Joseph and a neoclassical one dedicated to the Immaculate Conception. The main altarpiece is of baroque style, gilded and organized in three streets separated by Solomonic columns adorned with clusters. In the central street, above the tabernacle, the image of Saint Peter appears, dressed as Pope and seated on the throne. At the top, a canvas with Saint Peter kneeling and the rooster. In the lateral niches we find the images of San Antón and the Virgen del Carmen.
Hermitage of San Roque
It is a simple humilladero located in the center of town. It is rectangular in shape, with masonry walls reinforced with ashlars at the corners and at the access door. The interior is humble and bare and the only highlights are a stone basin for holy water and the image of San Roque, patron saint of plague patients, who appears dressed as a pilgrim. The construction of the hermitage may be related to the great plague epidemic that devastated the Segovian lands in 1.598 and 1.599. We do not know the incidence in Casla, but in neighboring Santo Tomé del Puerto, a third of the population died in just two months.
Hermitage of Our Lady of the Star.
Our Lady of the Star is the patron saint of Casla, and her hermitage rises between junipers and elm trees, at the very foot of the Sierra. Next to the hermitage stands the house of the santeros who took care of the place and which is now uninhabited. The building is austere, with plastered masonry walls, and ashlars in corners, cornices and openings. It consists of a single nave topped with a square presbytery, behind which is the Virgin's dressing room. Inside there is a hemispherical dome decorated with ornate frescoes with plant motifs that are grouped into eight "segments". The main altarpiece is in the Baroque style, and in the central niche it houses the image of the owner and communicates with the dressing room, from where it can be accessed to dress and adorn it.
Forge and shoeing colt.
They are two witnesses to forms of life that are already extinct and were very important for the development of daily tasks. The shoe rack is made of juniper, a wood of excellent quality that is very abundant in the area. The second is now used as a warehouse. The blacksmiths played a fundamental role in the economy of the towns, as they manufactured plowshares, the metal parts of the carts, horseshoes for draft animals ... etc. Sometimes they also acted as farriers, so the forge and the colt usually appear together.
The function of the shoeing foal is to immobilize the animals and avoid kicks, blows or goring. Depending on their ownership, the foals could be private or communal, from the entire neighborhood.
Recreational Area Nacimiento del Río Caslilla.
The recreational area is located next to the N-110, very close to the building of the old bullpen of the town, which today is the headquarters of the La Colodra association. We can find benches and tables, abundant shade, and a peculiar fountain that is operated with a crank that moves a small traditional wheel, restored by the residents of the town. Next to the recreational area, cross the river, flanked by the traditional stone walls of the adjoining orchards.

It runs entirely within the Sierra Norte del Guadarrama Natural Park and has a length of 7, 10 km. It joins the towns of Sigueruelo and Casla. Along the way we will cross mountain areas where centennial specimens of junipers appear. Arriving at the banks of the Caslilla, we will be able to appreciate the cuts and gorges that the river has gone into the limestone rock, and among which we find an area rich in caves, the Ranchón cave standing out.
