Scattered throughout the Spanish countryside and inside Spain’s cities are ghostly concrete remnants of the Spanish Civil Conflict. If the place to look, aren’t afraid of the occasional palm sized spiders and dare to trespass, these largely deserted and typically repurposed monuments of Spain’s bloody historical past are well worth the sweat and threat to discover.
In October 2024, I traveled to Spain to tour the Aragon province and take part in a Spanish Civil Conflict dwelling historical past show with Divulga Historia Frente Andaluz, a Spanish newbie historic affiliation devoted to preserving the tales of Spain’s civil warfare.
Previous to my journey, I had solely communicated with their members on-line, buying and selling images and ideas about Spanish Civil Conflict historical past. After they invited me to Spain to affix them for one in all their many packages, I knew all these hours spent studying Spanish in highschool would lastly repay. These newfound mates of mine made this story doable as a result of they confirmed me the instruments wanted to search out the long-lost combating positions that dot Spain’s panorama: Google Maps and unique images.

Tracing The Previous
From floor stage, previous fortifications are sometimes hid in plain sight. They’re usually positioned inside agricultural fields, in valleys and behind deserted stone homes. With the assistance of a Google Maps satellite tv for pc view, the lengthy eroded trenches come out vividly as winding snakes over the tops of the dusty Aragonese hills, and the bunkers like oddly symmetrical boulders.
It appeared to me like virtually each main street south and east of Zaragoza nonetheless extant from 1936, had some concrete defensive bunkers and trenches close by to defend it. These landmarks of warfare by no means went away. When the Spanish Civil Conflict ended, the Nationalist troopers that after occupied these positions went again to their houses, wanting to neglect the bloodletting that tortured their nation for greater than two and half years. For Republican troopers and civilians, dropping the warfare meant years of imprisonment (and typically execution) or exile. It’s no surprise the bodily landmarks of warfare step by step slipped from reminiscence and fell into decay.

Belchite
After renting a automotive in Zaragoza, I drove 35 minutes in the direction of the A222 freeway turning to the Belchite battle entrance. This website noticed months of intense combating starting with the large Republican offensive in the summertime and autumn of 1937. Zaragoza was a main goal of that offensive as a result of it was the most important metropolis within the area–and deeply vital to the Catholic trustworthy that supported the Nationalist Spain. The Republican thrust received badly stalled across the small city of Belchite. Belchite’s vastly outnumbered defenders managed to carry out for 2 weeks regardless of repeated artillery, aerial bombing, tank and infantry assaults. The Nationalist protection of Belchite was nothing wanting heroic. Actually, the town is preserved to this present day in its totally ruined state as a monument to the struggling and destruction of the Civil Conflict. It’s a must-see if you happen to go to the world.
For all their navy efforts, the Republicans didn’t maintain onto this space for very lengthy. By the Spring of 1938 the Nationalists launched a large offensive of their very own. They rapidly regained all of the territory they misplaced and extra.
Z-M-5 Los Barbis’ Concrete Fortifications

In 1936, the yr earlier than the Republican offensive in the direction of Zaragoza, the fifth Zapadores-Minadores (fifth Sapper-Miner Battalion), a Nationalist Military engineer unit, labored to construct quite a few defensive works to fortify the area in opposition to Republican assault.
In contrast to Republican engineer items that usually constructed impermanent fortifications with un-mortared stacked stone and wooden, the fifth Zapadores-Minadores used fashionable development strategies.
They significantly relied on poured concrete to construct strong constructions. Many nonetheless stand immediately since destroying them was simply an excessive amount of work. The fifth Sapper-Miner Battalion was pleased with its work and sometimes marked it with their unit designation “Z-M-5” or their nickname “Los Barbis.” It interprets as “The Beards”.

The primary of the fifth Zapadores-Minadores works I visited was a large bunker. This fortification regarded like it might have been completely at residence in Rommel’s Atlantic Wall defenses alongside the coast of France.
In its current environment, this particular fortification could possibly be simply mistaken for the muse of a long-gone picket home. The world surrounding it was overgrown with excessive grasses. The fortification itself was nestled on a strip of floor barely broad sufficient for it. It presently sits between fashionable railroad tracks and a graffiti coated freeway overpass. Sadly, it was fully sealed and I couldn’t get inside. It’s widespread for these previous defensive works to be sealed or crammed in.
About 1,000 yards away and a part of the identical defensive system, I discovered a well-preserved pair of conjoined machine gun bunkers that now stand guard, incongruously, over a cornfield subsequent to a contemporary delivery warehouse. Earlier than the harvest, tall corn stalks render these positions nearly invisible.

The Belchite Bunkers

After parking on the warehouse service street close to a derelict farm dwelling, I found a contemporary concrete irrigation channel that stood above the chest excessive grass alongside the sting of the sphere. After 5 minutes of “steadiness beam” strolling on the facet of the channel, the primary twin bunker got here into view. Take away the trimmings of modernity together with your thoughts’s eye, and also you’ll see your self within the Nationalist entrance line positions.
Dealing with east in the direction of a significant street junction, the machine gun crews in these positions supplied overwatch on the A222 and N232 south east of Zaragoza. The reminiscence of the August 1937 Republican offensive stays in sporadic bullet impacts pockmarked all around the bunker’s exterior face.

Since these positions have been a lot tougher to achieve and clearly on non-public property, there was no graffiti on them. To my delight, they weren’t sealed off both. Their interiors have been related, with ammunition alcoves solid into the partitions and firing steps for riflemen to shoot although the gun ports.
One bunker confirmed proof of being repurposed for contemporary wants. It had an improvised fire and excessive chimney. I believe farm laborers used it to prepare dinner their meals whereas working the fields. I guess they might have additionally discovered the bunkers’ thick partitions and roof pretty much as good shelter from the recent solar throughout their siesta.
El Saso

The best of the fifth Zapadores-Minadores defensive fortifications I noticed on the Aragon entrance was, certainly, El Saso. In contrast to the earlier websites, this one is nationally acknowledged, if little visited and open to the general public.
The largely cleared pillboxes and tunnels of this advanced are located on the plateau simply east of Belchite. It’s a bit of tough to search out as a result of there aren’t any directional indicators, the dust roads round it aren’t marked. It’s presently positioned behind a rubbish dump.
This elaborate combating place was manned with 250-350 males. It was additionally the strongest level alongside a 5 kilometer defensive position that encircled Belchite. El Saso additionally ran eastward towards the city of Azaila. The positioning has at the very least a half dozen concrete bunkers related with arched roofs and tile-lined tunnels. El Saso gave its defenders a protected panoramic view of the southern plain, the jap and northern slopes and roads beneath.
Mine fields and anti-tank defenses supplemented the defender’s rifles, heavy machine weapons and mortars. Within the occasion of gasoline assault, El Saso additionally had an underground poison gasoline shelter too. Nonetheless, it stays un-excavated. Navigating the winding tunnels and tight bunkers is less complicated if you’re underneath 5’9”.

A few of El Saso’s passages are nonetheless crammed in with soil and particles. Different tunnels and bunkers have misplaced their roofs and the above floor constructions just like the Paridera are collapsed. Generally, El Saso is in first rate form for one thing that withstood a lot combating. These positions have been a part of one of the crucial well-known and violent battles of the Spanish Civil Conflict. Each Nationalists and Republicans attacked, defended, captured and misplaced these positions.
Closing Ideas
Looking back, my expertise exploring these wartime historic websites was rewarding however a bit of odd too. I by no means encountered one other human being, Spaniard or in any other case. Had I seen somebody within the neighborhood when attempting to enter non-public property, I’d have politely requested for permission to go to the bunkers. There weren’t even any vehicles or occupied homes in sight.
I’ve no complaints about it. Extra historical past for me.
