Its church, of enormous proportions, is a magnificent Baroque temple attached to a monastery consisting of three large cloisters, which make it one of the largest in Spain. It is currently occupied by a community of Cistercian monks who have been attending the pilgrims in their hostel for centuries, on their way to Compostela. A few kilometres away we can visit the lagoon that attended the needs of the monks for centuries, in terms of water and fish supply and is included in the Red Natura 2000; It is definitely a good place to enjoy unhurriedly.

Of Romanesque origin, already before the year 1000 appeared as annexed to the monastery of Sobrado, passing later to depend on the monastery of San Martín Pinario, dependence that maintained until the secularization of the 19th century.

We must pass through the Bocelo mountains to reach this lonely church, a former Benedictine monastery, nestled in an environment of great beauty, next to a small river that descends from the slopes of the Bocelo. Outside we can see the remains of the work Romanesque and inside a set of 15th century frescos of great interest. .

At the top of Bocelo mountains we can take a short walk to discover the remains of ancient Neolithic mámoas or dolmens that are distributed throughout this mountain ridge, alternating with natural granitic formations attributed to the Moors.

It does not stop surprising this region and good example of this is the possibility of visiting this camp that takes us to the time of the Roman Empire; Here it was installed, until the 4th century, the Cohors I Celtiberorum formed by some 400 soldiers, although it seems that there was a subsequent reoccupation, by Germanic tribes, in the 7th century.

Not far from Ciadella we will be able to visit a cattle farm dedicated to the manufacture of cheeses and that also offers us the possibility of visits with children, enjoying with them a small zoo or a hiking route around the surroundings.
