Fortifications

As I said in a previous post, we decided to have four separate sections to our city, and in the centre would be our castle, giving us the opportunity to model different types of buildings and vehicles.

In this post I am focussing on the Military base.

What we need in the base to have;

  • Defensive structure
  • A training ground
  • Armoury
  • Military vehicles
  • Possible launch pad for aircraft?

I researched fortifications so that I could come up with a design that would in fact be suitable for it’s purpose.

The main points I found useful for the design are;

  • Ensure the attackers would have no where to hide, making them exposed for attacks
  • If the opposing troops are exposed they will also end up widespread and vulnerable
  • Have somewhere to drop projectiles to kill some of the enemies

I decided to use the “Polygonal Fortification” structure described in the book cited below.

It was low to the ground and had a ditch dug the whole way around so that for enemy troops to gain access they only had one real root of entering through the gate house.

I also aim to incorporate the tower structures into the design, whilst they were often isolated bases and therefore vulnerable, incorporated into the Polygonal Fortification, it should surely strengthen the design.

The tower has three levels. The bottom level is where the weapons are stored- with a shellproof roof, the middle level is the lodging for the troops, and the top level is the parapet. The first two levels are actually underground, so they are easily protected from most attacks. I intend to place the towers at each corner to remove the structural weakness that corners have on a building.

The base will be built on the outlying platform, applying the advice about having the structure isolated and making the enemy need to expose themselves in order to attack, removing the element of surprise. Also, as the structure is going to be built on a platform, there is no need for a ditch to be built around the parameter.

In my sketchbook are the possible designs for the military base.
