Prehistoric period

The mountains of Monfragüe house a great number of caves with prehistoric paintings from the Copper Age, Bronze Age and Iron Age for example the "Cueva del Castillo", located on the south face of the Sierra de las Corchuelas. Around the Park are remains of pre-Roman times. In Miravete remnants of an old castle exist, and in Malpartida de Plasencia there is an estate known as "El Calamoco". A warrior stele found in Torrejón el Rubio and the Treasury of Serradilla are evidence of a highly hierarchical agricultural society inhabiting this area.^[3]

Roman period

Remains of Roman roads, bridges, fountains and gravestones can be found, since the park is close to the Ruta de la Plata (Silver Route). A section of the route, which goes down to the bridge of the Cardinal from Villarreal, can be considered as a vestige of Roman road. As in almost all Spanish geography, valleys provide the layout for the road. Remains of watchtowers exist, in Cerro Gimio for example.^[3]

9th-19th century

During the ninth century, the castle of Monfragüe was built with five towers and two perimeters of walls. What is visible today are remnants of multiple restorations after military orders conquered it for King Alfonso VIII, with a round tower from the twelfth century and a pentagonal one from the fifteenth century.^[3]

In 1450, Juan de Carvajal ordered the Cardinal's Bridge to be built entirely from granite ashlars; it facilitated communications between Plasencia and Trujillo. Since the bridge was practically the only one crossing the Tagus in the Extremadura, it gave rise to pillage, turning the area into a "paradise" of bandits and robbers hidden in its steep and impenetrable mountain ranges.^[3]

At the beginning of the eighteenth century, the Spanish War of Succession seriously affected the area: The village of Monfragüe disappeared, inhabitants took refuge in the nearby village of Corchuelas, and the village of Piñuela at the other end of the mountain range was seriously damaged. Carlos III de Espana founded a village halfway between the "port of La Serrana" and the Puente del Cardenal, called Villarreal of San Carlos. It had a church, a fountain and barracks, but in spite of the privileges granted to its inhabitants, it never became more than a small village linked to Serradilla due to the danger and poverty of the area.^[3]

The Spanish War of Independence destroyed the Castle of Monfragüe, the Bridge of the Cardinal and Castillejo del Pico in Miravete and Corchuelas, whose inhabitants fled to Torrejón the Rubio, Serradilla and Malpartida de Plasencia.^[3]

20th century

During the Spanish Civil War in the nineteenthirties, the Extremadura was taken over rapidly. Rather than the conflict itself, the worst aspects were the hunger and poverty which followed. The impenetrable mountains with their maquis shrubland of the region were important to the highlander groups commanded by famous guerrillas like "Quincoces",^[4] "Chaquetalarga" (Joaquín Ventas Cintas) and "the French" (Pedro Díaz Monje),^[5]

In 1966, construction of the dam at Torrejón el Rubio, and the Alcántara Dam in 1969 altered the landscape irreversibly, as it submerged the wild beauty of the Tagus riverbanks along with its ecological and ethnological wealth.^[3]

In 1968, Jesus Garzón arrived in the area, enamored of the beauty of Monfragüe and dedicated himself to nature conservation. He battled with the administration, the owners of neighboring estates, politicians and mayors of the area, but his commitment, supported by scientists and nature lovers resulted in the April 4, 1979 declaration of Monfragüe as a natural park, a lower level of protection than a national park.

In 1991, Monfragüe was declared as a Special Protection Area for birds,^[1] During the following years, the conservationist mentality, the infrastructure in Villarreal and publication efforts about the riches of the Park were strengthened. Since 2003, it has been recognised by UNESCO as a Biosphere reserve. In May 2004, it was enlarged to the actual ZEPA "Monfragüe y Dehesas del entomo", which covers 116,160 hectares.^[6] After twenty-five years Monfragüe became a national park by law on March 2, 2007.^[3]

At the end of 2016, the area also received recognition as a dark-sky preserve.^[7]

Birds

In 1988 the European Union designated Monfrague a Special Protection Area (SPA) for bird-life. The SPA (or ZEPA, the equivalent acronym in Spanish) extends beyond the park, where the nesting sites are concentrated, into the surrounding dehesas, which provide food for the birds.^[8]

Monfrague is an outstanding site for raptors, with more than 15 regular breeding species. including the world's largest colony of Eurasian black vulture (over 600 pairs),^[9] it has the world's highest concentration of imperial eagles (more than 10 pairs), a large population of griffon vulture (over 600 pairs), and several pairs of Egyptian vulture, golden eagle and Bonelli's eagle. The crags and cliffs on the north side of the river midway through the park draw photographers from all over Europe and the Americas. The government has built observation blinds throughout the course of the river.

Other breeding birds for which the park is important are black stork and Eurasian eagle owl and there is a high density of azure-winged magpie. It is also one of the few locations in Europe where white-rumped swift breed.

Other wildlife

Iberian Lynx survived for a long time before numbers decreased. They were reintroduced and have since been doing well. ^[9] Deer and wild boar live in the park.
