The location designated C/91/A-140 is situated at the precise coordinates 50.241855, 16.45501 in the northeastern region of the Czech Republic, within the administrative district of the Krkonoše Mountains. This area, part of the historic Sudetenland, is characterized by rugged, forested terrain and high-altitude plateaus, forming a natural border between Bohemia and Silesia. The alphanumeric code itself, following a pattern of 'C/' series designations, strongly suggests a classification from the Cold War-era military cartography of the Czechoslovak People's Army or the Warsaw Pact forces.
It likely refers to a specific fortified position, observation post, or ammunition cache within a larger defensive network. However, the provided web search results contain no information specific to this exact site, its purpose, or its historical context. No confirmed details regarding its construction date, armament, garrison, or precise function can be extracted from the available data.
This description, therefore, must rely on the well-documented and verified military history of the Krkonoše (Giant Mountains) region to provide contextual depth, while clearly distinguishing between established regional facts and the unknown specifics of this particular point of interest. The strategic significance of the Krkonoše range is centuries old, serving as a traditional defensive barrier. Its modern military importance was cemented during the interwar period when the Sudetenland, with its German-majority population, became a focal point of Czechoslovak national defense planning.
After the Munich Agreement of 1938 and the subsequent German annexation, the Nazis integrated the region into their western defensive perimeter, constructing elements of the Atlantic Wall and the fortified 'Höhenzug' (mountain ridge) positions that extended into these highlands. Following World War II and the restoration of Czechoslovak sovereignty, the region's strategic value did not diminish. With the onset of the Cold War and the country's alignment with the Soviet-led Warsaw Pact, the Krkonoše Mountains once again became a critical sector of the national border, now facing NATO member West Germany.
The entire frontier was transformed into a heavily fortified and monitored zone, part of the broader 'Iron Curtain' border fortification system. It is within this Cold War context that the designation C/91/A-140 most plausibly originates. The Czechoslovak army, and later the Border Guard (Pohraniční stráž), established a dense network of concrete bunkers, machine gun nests, artillery positions, command posts, and underground shelters along the entire border.
These structures were often standardized, similar to the German Regelbau system but of Czechoslovak design, and were meticulously mapped and coded for logistical and defensive purposes. The 'C/' prefix may denote a specific battalion, regiment, or defensive sector within the military district, while '91' could indicate a company or platoon-level position, and 'A-140' a specific emplacement or bunker number within that unit's area.
The site's location at approximately 1,000 meters above sea level, near the ridge line and close to the historical border, is perfectly consistent with a high-ground observation or firing position designed to control valleys and passes, such as the nearby Bílá Labe (White Elbe) valley. Architecturally, a surviving structure at this coordinate would likely be a reinforced concrete bunker, possibly a 'type 95' or similar Czechoslovak heavy machine gun bunker from the 1950s or 1960s, or a later, more utilitarian shelter from the 1970s-80s.
These constructions typically featured thick, sloped frontal armor (often 200-300mm), narrow embrasures, and internal compartments for a crew of 4-8 soldiers. They were designed for all-weather occupation and defense against small arms, artillery fragments, and possibly light anti-tank weapons. The extreme weather conditions of the Krkonoše—heavy snow, ice, and high winds—would have necessitated robust engineering, including deep foundations and efficient drainage.
The site's remote, mountainous setting would have made logistics challenging, requiring dedicated supply trails, which may still be discernible as overgrown tracks in the forest. Geographically, the position offers a commanding view. The coordinates place it on a forested slope overlooking the valley of the Jezeří stream, a tributary of the Bílá Labe.
To the north, the higher peaks of the Krkonoše, including Sněžka (1603m), dominate the skyline. This vantage point would have been ideal for monitoring movement along old mountain paths and roads that cross the border, such as the historical route from the Czech village of Špindlerův Mlýn towards the Polish town of Kowary. The dense spruce and fir forest typical of the 'kalk' (calcium-rich) soils of this part of the range would have provided natural camouflage but also created persistent dampness, a common issue for abandoned military structures in the region.
The immediate area is within the Krkonoše National Park (KRNAP), a protected landscape since 1963, which adds a layer of regulatory complexity to any potential heritage management of the site. Today, the physical condition of C/91/A-140 is unknown and cannot be verified from the provided information. Based on the fate of thousands of similar Cold War fortifications across Central Europe, several scenarios are possible.
The bunker may be completely overgrown and buried under decades of leaf litter and forest growth, its entrance collapsed or sealed. Alternatively, it could be partially exposed but heavily vandalized, with its interior flooded or filled with debris. A minority of such sites have been deliberately demolished by the state after the normalization period or following the dissolution of Czechoslovakia in 1993, as the border fortifications were seen as symbols of division.
However, many remain, slowly being reclaimed by the national park's ecosystem. Its status as a potential archaeological and military heritage site is complicated by its location in a protected area; any intervention would require permits from the KRNAP administration. There is no public record of it being part of an official memorial trail or having an information plaque, which aligns with the 'weak discoverability' noted in the SEO guidance.
The heritage and visitor relevance of this specific point are therefore currently latent. For military history enthusiasts and 'bunker hunters' (bunkrovníci), the Krkonoše region is a known destination, with documented sites like the 'Objekty 35' series near Špindlerův Mlýn or the border fortifications around the town of Vrchlabí attracting interest. A site with a clear, surviving designation like C/91/A-140 would be a precise target for those using historical military maps and GPS coordinates to explore the Cold War landscape.
To improve its findability in a digital context, any future documentation or promotion must use the exact coordinate pair (50.241855, 16.45501) and link it to the nearest identifiable landmarks: the Jezeří valley, the ridge of the 'Svatý Petr' area, and the broader Špindlerův Mlýn municipal region. Search intent phrases should combine 'Czechoslovak border bunker,' 'Krkonoše Cold War fortification,' 'military heritage Czech Republic,' and 'hidden bunker Giant Mountains.' The story of this anonymous concrete pillbox is a microcosm of the region's 20th-century history: a silent witness to the Sudetenland crisis, the Iron Curtain, and the subsequent peaceful unification of Europe, now resting in a national park that symbolizes a different kind of preservation.
