Hoyo de Manzanares: where life has long revolved around stone

Hoyo de Manzanares

The entire municipal area of Hoyo de Manzanares lies within the Cuenca Alta del Manzanares Regional Park and in the sphere of influence of the Sierra de Guadarrama National Park. This setting gives the town exceptional natural value, with abundant plant and animal life. Just 35 kilometres from Madrid, Hoyo also offers compelling heritage sites and deeply rooted traditions.

History

It can reasonably be assumed that the area now occupied by the municipality of Hoyo de Manzanares has been used since very early times, following natural paths and the banks of local streams—strategic locations for settlement.

Archaeological remains from the post-Palaeolithic period found across the Sierra de Madrid appear to point to a gradual increase in occupation during a phase of improving climate. From the Neolithic onwards, settlements became more stable, with a largely pastoral economy and, to a lesser extent, agriculture. During the megalithic period, evidence becomes more striking thanks to the record left by large carved stones linked to spiritual practices. Later, with the Carpetanian Celtiberian culture, technology developed and became more specialised.

It was, however, under Roman culture—established across Hispania—that social organisation changed most profoundly. Hoyo de Manzanares, as a rural community in the late Roman world, is thought to have played an economic role connected to livestock, mining and agriculture, among other activities, with specialised trades including stone quarrying. Its geographical position—on routes between important medieval population centres—would also have made it a natural stopping point for travellers.

Evidence from this period is scarce but promising. With the arrival of the Visigoths, a feudal system took shape—one of the defining features of the Middle Ages.

Recent archaeological discoveries appear to confirm the hypothesis of an early, stable rural settlement in Hoyo de Manzanares, possibly dating to the Roman period. Archaeohistorical research has revealed a necropolis with phases from late Roman, Hispano-Visigothic and medieval times, currently being studied in an area of La Cabilda Municipal Park. Two main types of tombs have been identified: granite, bathtub-shaped sarcophagi oriented east–west, and cist graves oriented north–south.

Other highly significant remains have also been found, including a stretch of a secondary Roman road (now lost to time) and areas reserved for agricultural activity. During the Middle Ages, under Muslim rule, the area was used for territorial defence under the authority of Magerit (Madrid), and two watchtowers (or observation towers) were built within the municipal limits.

The definitive foundation of the settlement dates to 1636. As for its name, the town was originally known as “El Oyo de Manzanares” and, centuries later—around 1787—it became “El Hoyo de Manzanares”, with the h incorporated.

After its foundation, Hoyo de Manzanares—like many towns in the region—was shaped by long-standing territorial disputes between Segovians and Madrilenians. These conflicts lasted for centuries and involved prominent monarchs such as Alfonso VII, Alfonso VIII and Ferdinand III, culminating in the reign of Alfonso X “the Wise”, who created the Real de Manzanares, a grouping of municipalities in the Sierra de Guadarrama intended to end the ongoing confrontations.

Despite Alfonso X’s efforts, disputes continued. Sancho IV returned the lands to Segovia in 1287, and later John I granted them in 1383 to the Hurtado de Mendoza family, linked to the Ducal House of Guadalajara.

In the 15th century, Hoyo de Manzanares became part of the forests and woodlands of El Pardo as a royal hunting preserve, turning it into a favourite setting for royal hunts. This reduced the area’s livestock and agricultural activity—the main economic pillars of the time—and caused significant tension among the population, who complained that hunting and game animals damaged forests and farmland and hindered agricultural development.

Once again, there is a documentary gap spanning the 16th to 18th centuries. The Carlist Wars led to the destruction of records when the troops of Carlos of Austria invaded Madrid and occupied and looted towns across the Sierra de Madrid. Even so, it is known that in the 17th century the construction of the Church of Our Lady of the Rosary, begun in the 15th century, was completed. It is also recorded that in 1636 Hoyo de Manzanares was granted the status of villa, becoming jurisdictionally independent from the Real de Manzanares—although it remained under the Mendoza family.

The earliest socio-economic data come from the Cadastre of the Marquis of Ensenada (1752). It describes Hoyo de Manzanares as a lordship belonging to the Duchess of the Infantado, who held rights including the alcabalas, martiniega, the appointment of justice and chief officer, and the right to unclaimed property (mostrenco) and chamber penalties. The document also records 70 households in mid-century and 400 households by 1789, a rise attributed to low adult and infant mortality and the high quality of life offered by Hoyo’s environment and natural resources. Several documents from the time highlight the quality of the physical setting, especially its climate, altitude and distance from rivers and marshes associated with disease.

Economically, the transport of firewood and stone produced locally was the main livelihood, with Madrid as the principal market—demanding firewood for heating and stone for construction and paving.

A century later, in the 19th century, the economy continued to focus on selling timber and local granite to Madrid, complemented by agriculture, particularly cereals. Travel to Madrid and Colmenar Viejo at the time was by pack animals.

Also in the 19th century, a civil confiscation process (desamortización) had a major social impact on Hoyo de Manzanares, as it was one of the municipalities with the largest surface area sold into private hands. Much of this land became large estates devoted to leisure and hunting.

In the 20th century, the establishment—north of the town—of the Army Engineers Military Academy had a significant impact, driving strong population growth from 1947 onwards. The 1955 official register recorded 2,165 inhabitants, a growth rate of 500% compared to 1900.

Hoyo de Manzanares’ reputation as a “healthy municipality” not only attracted well-known figures drawn by its sanatorium, but also strengthened tourism. Today the town continues to grow, with new residents settling in modern developments; during holiday periods, Hoyo can reach around 20,000 people.

Culture

Variety is the hallmark of Hoyo de Manzanares’ streetscape: churches, monuments that speak of earlier times, a Town Hall to admire—these and many more details lend style and character to the town’s corners.

Former Parish Church of Our Lady of the Rosary

Plaza de la Caldereta

Construction began in the 15th century and was not completed until the 18th. Over time, this granite building underwent numerous restorations, the most recent transforming it into a Cultural and Social Centre. The stage arch was altered so the central nave could become an auditorium with seating for 150 people.

One part remains in religious use: the chapel dedicated to the town’s patroness, the Virgin of La Encina, set in one arm of the crossing.

Town Hall

Plaza Mayor, s / n.

Set on the Plaza Mayor, a traditional Castilian arcaded square built entirely in granite. The Town Hall is the most emblematic building: two storeys, with an off-centre tower adorned with pinnacles and stone spheres, as well as a clock and the town’s coat of arms.

Fuente del Caño

The fountain, built entirely in granite, is located in Plaza Mayor, a typical Castilian square with porticos.

Stonecutters’ Monument

Plaza Cervantes, s / n.

A tribute to stone quarrying and masonry—until around 1960, one of the town’s main livelihoods. It consists of a small obelisk topped with the village crest and a commemorative plaque.

Parish Church of Our Lady of the Rosary

Paseo Mayor, s/n
A more recent parish church, as the previous location (the former parish church) is now used in part as a cultural centre.

Plaza de la Caldereta

An irregular square dominated by a large stone block topped with a cooking pot—symbolising the Caldereta, a much-loved event during Hoyo’s festivities. The square leads into the group of municipal buildings.

La Cabilda Archaeological Site

Camino del cementerio, 11

Ongoing work at La Cabilda has revealed a small, village-type settlement dated to the 7th–8th centuries AD, pushing local origins back by six centuries to the Visigothic period.
Granite-built structures were found, once roofed with tiles, with hearth remains inside—fires used for cooking and warmth. Artefacts recovered shed light on daily life and work: knives, mortars, hand mills, wool carders and spindles, alongside items linked to more complex trade activity such as weights and iron ingots.

Festivals and traditions

Traditional—yet constantly refreshed. That’s the spirit of Hoyo de Manzanares. Most celebrations honour patron saints and virgins, punctuated by community meals, bull-related festivities and, above all, plenty of dancing. Summer nights also come alive with cultural events and open-air activities.

• Festivities of the Virgin of La Encina (8 September)

The main day features a procession followed by demonstrations of traditional games. In the surrounding days, there are bullfights, sports tournaments, fireworks, open-air dances and cultural events. The Caldereta is a highlight: more than 1,000 kilos of fighting bull meat are served.

• Pilgrimage (early October)

A procession in honour of the Virgin of the Rosary, followed by a country-style communal meal in La Cabilda Municipal Park.

Nature

Hoyo de Manzanares is rich in flora and fauna. Vegetation is largely woodland, with areas of scrub and grassland. Wildlife is dominated by bird species. The entire municipality lies within the Cuenca Alta del Manzanares Regional Park—the foundation of Hoyo’s remarkable landscape and natural value.

La Cabilda Park and Recreation Area
