The Chinese Navy is building a string of overseas bases. So far the largest and furthest afield is in Djibouti on the Horn of Africa. This strategically-located base appears ready to receive large warships, maybe even aircraft carriers. One aspect of the base is particularly interesting: It is a modern-day fortress built from scratch. If the Communist country was hoping to give off non-imperialist vibes as it expands its presence overseas, then it may have chosen the wrong architects.
And it is not just castle aesthetics, the base really is designed to be highly defendable on a scale rarely seen, even in war zones. Construction of the walls started in early 2016, and was substantially complete by spring 2017. The base has been built up since.
Approaching by road, you first have to turn off the perimeter road and pass through a substantial automated outer gate. Turning 90 degrees, always good for slowing vehicles down, you then pass through two vehicle checkpoints and a chicane. Eventually the main gate is in sight. It appears to have last-ditch pop-up vehicle barriers and large concrete doors.
If you you tried to circumvent the vehicle route described above, you would face many layers of defense. First there is a high perimeter fence which separates the public road from the private perimeter road. Then there is another high fence with razor wire before you climb up a steep slope to the outer wall. This is made out of ‘Hesco’ style barriers with razor wire along the top. Hesco barriers are wire frames filled with giant sandbags. They are commonly used by Western forces in Afghanistan and Iraq as the main walls of fortified bases. Here they are relegated to just being an outer wall.
Inside the Hesco wall is the main wall built out of concrete. It has crenelations, meaning the up-and-down style battlements familiar from medieval castles. There are also gun loops, which are holes to fire weapons through. And there are tall towers on the corners.
