# Agoncillo, La Rioja

Agoncillo (Spanish pronunciation:) is a town and municipality in La Rioja province in northern Spain.
Club Deportivo Agoncillo is a football team based in Agoncillo.
It is believed that the name comes from an ancient Celtic settlement named Egon whose ruins lie near the town. The area was also populated in Ancient Roman times. Agoncillo is strategically located near the Ebro River, which historically marked the boundary between Castile and Navarre. It sits close to where the Jubera and Leza rivers converge, with the Leza River flowing into the Ebro nearby. This positioning allowed the town of Agoncillo to control the passage of these rivers and oversee the important road running through the area. The current town is believed to occupy the site of the ancient and now ruined settlement of Egón, from which it derives its modern diminutive name.
The theory of its Roman origins is further supported by the presence of a documented road that passed nearby, an important route during the Middle Ages. Historically, Agoncillo has appeared under various names, including Agonciello, Egonciello, Agusiello, and Sagonciello.

## History
### 11th century

On January 26, 1056, King of Navarre sold Agoncillo (then called Sagonciello) and Villanueva to Sancho Fortunionis and Blasquita. They later transferred the town to the Monastery of San Juan de la Peña in exchange for a horse and ten oxen. In 1066, Queen Estefanía bequeathed Agoncillo to her son Ramón, along with other nearby properties.
Following the murder of the Navarrese king in 1076, the region came under Castilian control, and King Alfonso VI placed it under García Ordóñez’s governance. By 1168, García Bermúdez held Agoncillo for the Navarrese king, but Alfonso VIII later recaptured it. In the sentence given by Henry I of England, the right bank of the Ebro was assigned to Castile, making Agoncillo a crucial frontier defense.

### 12th century

The lordship of Agoncillo was given to Bermudo de Azagra, the lord of Agoncillo, by the grace of Emperor Alfonso VII. His line ends with his third granddaughter, Doña Teresa Fernández de Villalobos, married to Fernando Alvarez de Lara, lord of Valdenebro. In 1182, Alfonso VIII expelled the Navarrese from Agoncillo and Arrúbal, indicating a repopulation effort to strengthen the frontier.

### 13th century

In approximately 1211, a captain of the Medrano family held the lordship of the castle and town of Agoncillo. Medrano's son was suffering from a mysterious and untreatable ailment. In 1211, Francis of Assisi roamed those very paths of Agoncillo. In a saintly manner, he visited Medrano's castle of Aguas Mansas in Agoncillo, placed his mystical hands upon the ailing Medrano boy, and miraculously healed him, securing the Medrano lineage in the lordship of Agoncillo. This act ensured the continued prominence of the Medrano family in Agoncillo, which remains renowned for its reverence toward the humble saint of Assisi. The Medrano family generously donated some land, including a tower, situated close to the Ebro River within the city of Logroño as a gift to Saint Francis, establishing the first Spanish convent of his Order there. Unfortunately, despite its centuries-long legacy of glory and sanctity, the convent met its demise in the 19th century due to the advent of liberalism and its accompanying laws. Today, the remnants of its walls still remain.
The noble Don Pedro Gómez de Medrano, Lord of Agoncillo (b. 1285), married Doña Teresa de Salazar (b. 1288), the daughter of Garci III López de Salazar, lord of Estremiana and Cidamón in La Rioja, and Navarra de Zamudio. Together, Pedro and Teresa had a daughter, Doña Aldonza de Medrano y Salazar (b. 1315), who became the Lady of Agoncillo.

### 14th century

Alfonso XI of Castile granted the Lordship of Agoncillo to Sancho Sánchez de Rojas and Ursula Díaz his wife on September 1, 1336 in Lerma.
In 1337, Don Rodrigo Alfonso de Medrano, Chief crossbowman of King Alfonso XI of Castile, bought the village of Agoncillo, La Rioja and the castle of Aguas Mansas in Agoncillo from Sancho Sánchez de Rojas. Rodrigo Alfonso de Medrano started carrying out several remodelling works, adapting it to the style of the 14th century. In Rodrigo Alfonso de Medrano's testament in 1345, he noted having spent big amounts of money in "...building the castle and the village" (in Old Spanish "...fazer el castillo e la villa").
During the battles between Peter the Cruel and Henry of Trastámara, the castle passed onto the hands of Charles II of Navarre, although for a short period. In 1392, it was once again owned by Rodrigo Alfonso de Medrano, lord of Agoncillo, who bequeathed it to his nephew, Don Diego López de Medrano. In 1447, Diego's son Don Pedro Gómez de Medrano, gave his son Don Lope de Medrano the town of Agoncillo and San Martín de Velilla (northwest of Agoncillo).

While the early owners typically resided in Logroño, from the 16th century onwards, their descendants chose to live in Alfaro, where they also held substantial properties.

### Aerodrome

A military aerodrome was built in Recajo, a town within Agoncillo municipal term, in 1923. It was first known as Aeródromo de Recajo, but in 1932 at the time of the Second Spanish Republic its official name was changed to Aeródromo de Agoncillo. Located about 10 km from Logroño, since 1939 it housed the Maestranza Aérea de Logroño of the Spanish Air Force with the Regimiento de Bombardeo Nº 15, Escuadrón 110 that operated Heinkel He 111 bombers until the late 1950s.
After the bomber squadrons were phased out, the aerodrome reverted to civilian use as the Logroño-Agoncillo Airport. It now has a smaller airstrip and houses a museum.
