Battle of Brunete and Madrid Front
Sierra Oeste
Enjoy a weekend of history and nature by visiting some of the best-preserved vestiges of the Spanish Civil War in the Community of Madrid. Here you will find Blockhaus 13 in Colmenar del Arroyo, the starting point of this route that will take you through the pastures of Fresnedillas de la Oliva and Navalagamella. There you will discover the remains of interesting blockhouses that dot a landscape of holm oaks, overflown by eagles and vultures, as it is located in ZEPA 56 (Special Protection Area for Birds), one of the main bird reserves in the Community.
We recommend staying in Santa María de la Alameda and starting your second day of excursion there, enjoying its silent mountainous landscape while visiting the blockhouses of Las Herreras.

Blockhaus 13 is an imposing reinforced concrete fortification about two kilometers from Colmenar del Arroyo. The blockhouse has about 160 square meters of floor space and consists of a main body with a 10-meter diameter from which four smaller nests are accessed, all with loopholes that allowed it to control the entire surrounding terrain. This building constitutes the highest expression of Civil War military architecture in the Community of Madrid.

North of the municipality of Fresnedillas de la Oliva, there is a set of very well-preserved blockhouses consisting of shooter parapets with embrasures, trenches, covered machine-gun nests, and communication distributors. These blockhouses are probably one of the best examples of military architecture in the center of the peninsula in their category.

The blockhouse-bunkers are perfectly visible from the road. The best grouping is located on the western slope of a hill, halfway between the Horcajo house and the Alarcón house. They are three fortifications of irregular shape due to the proximity between the machine-gun nests. The cylindrical building served as accommodation for the detachment stationed there. From this point, the ruins of several buildings destroyed during the war can also be observed.

Blockhouse Location
The border of Madrid and Ávila witnessed the first combats of the Civil War. The blockhouses are located on Peña del Águila to the north, on Alto de la Mora to the south, and on Alto de Las Herreras. These blockhouses were part of a National Front military complex and were built between 1936 and 1939, taking advantage of the steep terrain, which provided natural defense. Here we can also find remains of trenches, machine-gun nests, as well as spectacular landscapes.

An exhibition space dedicated to the role of women during the Spanish Civil War is located in the rehabilitated building of the old schools. The exhibition traces the role of women during the conflict, which began in 1936, highlighting various associations and relevant female figures from the early 20th and late 19th centuries.

Battle of Jarama
Las Vegas & Alcarria
The best way to travel this artery of history and nature is by taking your bike or walking along the 40-Day Railway Route.
Start your route in Villar del Olmo, where you will learn about Civil War testimonies that will take you through Orusco de Tajuña, Carabaña, Valdaracete, and Estremera. Besides the interesting history of this route, the path will take you through a beautiful agricultural landscape of olive trees, vines, and cereals, through rock walls excavated for the railway, sometimes passing under stone bridges.
Extend your route along the Vía Verde del Tajuña; from Carabaña, you can reach Tielmes, Perales de Tajuña, and Morata de Tajuña, where you can continue discovering the vestiges of one of the bloodiest confrontations of the Civil War: the Battle of Jarama. Between the sections from Morata to Perales, you can see the unique Risco de las Cuevas.
Also, you are in a land of wines. Are you going to leave without trying them?

Greenway of the 40-Day Train or Negrín Route
During the Spanish Civil War, Madrid was almost besieged, except for the gap between the current Barcelona and Valencia roads. During the years 1937 and 1938, this railway line was created in «40 days» to connect the two lines: Madrid-Zaragoza and Madrid-Levante, so that the capital would not be isolated and lack supplies.
Its purpose was to supply food and weapons to Madrid. Once the war was over, this railway had no purpose, and in the early 1940s, it was dismantled.


Villar del Olmo Section
Length: 12 km
Difficulty: low. Circular
Route start
The path runs along the valley slope, passes through several tunnels, and has viewpoints and the possibility of connecting with other paths such as the Cañada de las Merinas and the route to the Escurrizo fountain, a stopping and resting point to quench the thirst of shepherds and animals that traveled the livestock trail.
Villar del Olmo, Orusco de Tajuña, Carabaña, Valdaracete, Estremera
Length from Carabaña to Estremera: 15 km
Difficulty: medium-low. Linear
View location
This route is very easy and pleasant to do, as the entire path is asphalted and also free of road traffic (although caution is needed at road crossings). It is exciting to pass through its tunnels and also through its trenches: paths cut «with a knife» that cross the hills, and which now form cuttings where you can walk, both on foot and by bicycle. In Carabaña, the route coincides for a section with the 40-Day Railway Route.


Vía Verde del Tajuña. From Carabaña to Tielmes and Perales de Tajuña
Length from Carabaña to Tielmes: 7 km.
Length from Tielmes to Perales de Tajuña: 6 km.
Difficulty: low. Linear
The route runs through an agricultural landscape with gentle profiles, without ramps. Near Carabaña, there is the Chávarri station, once the warehouse for the famous «Aguas de Carabaña», and in Tielmes, the most representative Neolithic dwellings in the area. Our red track leads us smoothly to El Risco de las Cuevas, a complex of 47 artificial caves located on the right bank of the Tajuña River, which have been declared Assets of Cultural Interest.
A recommendation:
We recommend you go from Perales via the Vía Verde to Morata de Tajuña to visit the museum and the park of the Battle of Jarama. And come to the Battle of Jarama days in Morata de Tajuña, on the second weekend of March, where Morata becomes a living museum thanks to historical reenactments, guided tours, conferences, and screenings.

On this section of the Vía Verde del Tajuña, on the way to Perales, we can see two vestiges of what was called the «2nd Defense Line of the Jarama», built by the Republican army: a machine-gun nest in excellent state of conservation and an immense cave where troops took shelter.


The Somosierra Front and the Water Front
Sierra Norte
From the beginning of the War, the defense of the Puentes Viejas and El Villar reservoirs, vital for supplying water to Madrid, kept this front in permanent tension.
Start your day by taking the Somosierra Front route. A 2.5-hour visit of great historical interest that covers the front line of both sides, allowing you to observe a wide variety and quantity of military construction remains such as machine-gun nests, an observatory, trenches… In addition to other sites such as troop kitchens or the supply center.
Spend the night in Piñuecar-Gandullas, and the next day head to Paredes de Buitrago to visit the Water Front. Start by visiting the Interpretation Center of the Water Front. This route of approximately 3 hours has the largest concentration of preserved war infrastructure from both sides.
Piñuecar-Gandullas
Somosierra Front
Length: 7.4 km
Difficulty: 2 / 5. Circular
Route start
A route of medium difficulty if we climb Cerro de Piñuecar. Another of the jewels, in terms of historical routes, in the Sierra Norte. It covers one of the most important fronts of the Spanish Civil War and one that remained active for the longest time. This circumstance has left us with a multitude of war infrastructure from both sides.

Loma Quemada Position
Water Front Location
A very complete historical itinerary on one of the most important events of the 20th century: the Spanish Civil War. It allows you to learn about the different war infrastructures of both sides due to the proximity of both fronts.
Interpretation Center of the Water Front
At the start of the Route (Paredes de Buitrago), there is an interpretation center for the Water Front route; visiting it will help us put this historically and patrimonially valuable route into context.

A recommendation:
Take the guided tours: “Between trenches and water: the passage of the Civil War in the Sierra Norte” and “Paredes de Buitrago, a fortified town”.
Dare to take the cycling route that starts in Buitrago del Lozoya:
“On the front line. Civil War in the Sierra Norte”
Length: 41 km
Difficulty: 4 / 5. Circular
Route start
Through the common thread of the Civil War in the Sierra Norte and the valuable war infrastructures that are preserved, we propose a cycling route to enjoy the tranquility of the mountain paths and roads while touring the water front and the Somosierra front.

The Guadarrama Front
Sierra de Guadarrama
Nature and history go hand in hand in a landscape of great beauty, such as the Sierra de Guadarrama, a transit area between the two plateaus over the centuries through various passes and cols, which therefore became a transcendental space for both sides during the Civil War.
The conflict thus left numerous vestiges of war constructions in the territory of the municipality of Guadarrama, generally in strategic locations accompanied by environments of great natural and visual beauty.
These remains, essential to our history, have been preserved defiantly despite all the new uses of the Sierra. They are interesting both for their historical significance and the many legends surrounding them, as well as for the richness of the natural heritage that houses them. Respect for the past leads to the desire to preserve and better understand these places that invite long and interpreted visits.
