The trees are surrounded by a wide range of bush species, such as hawthorn, heather, blackthorn, juniper, wild rose, blackberry, rockrose, and gorse.

[3] Monte Alto occupies a smaller area and is populated almost completely with beech and Pyrenean oak trees, as well as a small repopulation of Pinus sylvestris.

In this diverse landscape birds of prey such as goshawks and sparrow hawks can be found, while black kites are often seen in open spaces.

Among mammals, squirrels are abundant due to the large amount of tree cover, with field mice, wild boar, foxes and badgers also seen.

[3] Documents from the time period suggest that the existence of Grañón dates back to the 9th century, when the king of León, Alfonso III, ordered a castle to be constructed on top of a hill located next to the village, which was known as Mirabel or Mirabelia.

Under the protection of Grañón's castle, small hamlets and neighbourhoods began to develop, which gradually saw a population being established in the area.

[4] Grañón was involved in the territorial battles between Sancho VI of Navarre and Alfonso VIII of Castile in the second half of the 11th century.

In 1187, Alfonso VIII granted a fuero (a local jurisdiction) to the village, with which the urban planning of the new settlement was determined.

[citation needed] In 1995, the Grañonero singer Juancho Ruiz el Charro wrote the song La cruz de los valientes (The cross of the brave) which recalls the legend of Martín García.

[citation needed] The medieval layout of Grañón was orientated around the San Juan monastery (now the parish church), which the village grew around.

In Calle El Caño, there is a two-storey 18th-century house, with both floors made from ashlar and rubble masonry, lintelled openings and a balcony with iron fittings.

According to an unpublished study carried out by María Amor García Antolín, the oldest lavoir dates back to the 18th century and is situated at the end of Calle Las Cercas on the outskirts of town.

At the end of the 20th century a new stone fountain was constructed in Plaza del Hórreo, placed in a corner of the town hall's exterior, as an homage to pilgrims.

[7] Grañón has an important historical and artistic heritage associated with the growth that the town experienced during the Middle and Modern Ages, and with its close relationship to the Camino de Santiago.

[8] In terms of the interior, among noteworthy items are the baptismal font from the 12th century, the only part that remains of the original monastery, and the reredos dedicated to Saint John.

This is a work of rich ornamentation, built between 1545 and 1556, and formed by plateresque motifs and reliefs within which sculptures full of movement were created.

On the inside, the crossing is covered by a hemispherical dome with a cupola, while the rest of the nave is enclosed in a barrel vault with lunettes, supported on Corinthian pilasters and semicircular arches.

This is why it is located at the exit of the town, on the junction of the Villarta-Quintana, Morales and Corporales roads.Inside there is a cross which sits on top of a Tuscan column where the following inscription can be read: “Hizole Bicente clérigo beneficiado en San Juan de Grañon”.

Until recently, the chapel's altar was a mannerist altarpiece from the year 1540, in which Jesus can be seen being harassed and ridiculed by the Jews during the crowning with thorns in the presence of Caiaphas and Annas and other members of the Sanhedrin.

This altarpiece, belonging to the school of Damián Forment, was restored between the years of 2009–2010, and can now be found in the chapel adjoined to the parish church.

The most important are: Other events, that began to be celebrated at later dates, include: A street market takes place in Grañón every Wednesday, where a variety of products can be purchased.

Created in 1989, it publishes a magazine entitled Mirabel (previously La Voz Cultural), which is produced three times a year, containing articles that recount interesting stories about life in Grañón.

Among the young, an important group is the Cuatro Cantones club, which carries out various activities during the month of August, such as games for children and the sharing out of choricillo, a smaller form of chorizo.
