In Grisel, cultural and landscape features are clearly distinct: the Castillo retains medieval defensive features, the church dates from the 16th century, and the Pozo de los Aines is a water-formed doline. The town also has the San Jorge tradition and a GR hiking trail from the Plaza to Alto de la Diezma. This gives visitors a range of reasons to explore, from architectural history to geological features.
Castle, Church and Traditions
The Castillo de Grisel is protected as a Bien de Interés Cultural (BIC) in the Monument protection category and the Military category. Its existence is documented as early as 1106. The main façade retains a crenellated parapet with narrow arrow slits and an entrance with a pointed arch. A machicolation with three machicolations protects the door. These details give the castle a clearly recognizable defensive architecture.
The Iglesia de Nuestra Señora de la Asunción offers a different architectural accent. It was built of brick between 1549 and 1552. The single-nave church includes chapels, along with a star-shaped rib vault and plaster busts depicting apostles and saints. Compared with the castle, the focus here is on the design of a church interior: the nave, vault and figures are distinct elements of the building.
Local traditions also give Grisel its own cultural character. On April 23, the San Jorge tradition includes a pilgrimage to the chapel of Samangos, a return procession and the ceremonial greeting known as “cortesías” between the two processions. Samangos is an abandoned settlement in the municipality; its chapel is what remains. The Dance de Grisel is of the “pastorada” type. Its roles include a Mayoral, a Rabadán, an angel, a devil, a Cipotegato and eight dancers known as Paloteadores. Thus, alongside the buildings, there is both a procession tradition and a set of named characters and roles.
Doline and the Diezma Landscape
Grisel lies in the northern Somontano del Moncayo, at the foot of the eastern side of the Diezma, at an altitude of 625 metres. A notable geological feature is the Pozo de los Aines: underground watercourses formed a doline there measuring 22 metres in diameter and 23 metres deep. A height difference of up to 32 metres is also given. Diameter, depth and height difference describe different dimensions of the formation and should not be confused.
The moisture in the Pozo allows numerous moisture-loving plants to grow, covering its walls and floor. The site was rehabilitated in 2013 and has benches with tables, a fence, and a stone staircase with railings leading to a viewpoint with panoramic views. The geological formation, moist habitat and facilities at the site offer several distinct aspects to explore.
The GR hiking trail offers another perspective on the landscape. It starts at the Plaza de Grisel and climbs to Alto de la Diezma. It passes just a few metres from the Mirador de la Diezma. The trail and the doline represent different features: one is a rising route up to Alto, while the other is a landform shaped by water and its moisture-loving vegetation. Together, these features show why Grisel is connected both to its architectural history and to the landscape of the Somontano del Moncayo.
