Ancient Fortress and Moat in Inner Mongolia’s Desert

A Military Relic of the Cold War

In the vast expanse of Inner Mongolia’s desert, a fortified structure emerges, surrounded by an imposing moat. This site, originally identified through satellite imagery, showcases an artificial hill with meticulously designed earthworks and ditches. Built by the Chinese Army between the 1960s and 1970s, these fortresses were part of a larger defensive network near the border with Mongolia.

The central "mountain," ranging from 20 to 40 meters in height and 250 to 400 meters wide, served as an observation post and housed bunkers. Surrounding the hill are undulated trenches and earthworks, strategically designed to enhance defense. The layout resembles ancient pentagonal fortresses, a shape often chosen for its defensive advantages and potential symbolic meaning.

Advanced Military Planning

Satellite imagery has revealed not only the main fortress but also satellite sites, including triangular-shaped outposts connected by trenches. These auxiliary positions likely housed artillery batteries and other defensive installations, covering a 1-kilometer radius. This configuration suggests careful planning to optimize defense and minimize crossfire risks.

Another fortress in the region, the Hidden Fortress with Moat in Inner Mongolia’s Wilderness, shares similar design elements and strategic importance. Discover more about this intriguing site here.
