What it is Filled

In bastion fortification, a detached outwork, usually a narrow rampart with two faces, placed in front of a bastion or ravelin to protect its faces from direct fire and to delay attackers; the model describes historical fortification elements.

Why it exists Filled

Let an agent explain the counterguard as a historical fortification element, relay its function and examples from military architecture sources, describe its placement, and distinguish counterguards from ravelins, bastions, tenailles and lunettes.

Distinguishing features Filled

  • Detached outwork
  • Parallel faces
  • Protects bastion
  • Bastion system element

What robots and AI may and may not do Filled

Must not

  • Confuse counterguards with ravelins or other outworks.
  • Encourage climbing on or digging into fragile historic earthworks.
  • Remove material from a protected fortification site.
  • Present a reconstruction of a lost counterguard as surviving fabric.

Only with a human decision

  • Any physical intervention on a surviving historic counterguard.

May

  • Explain the counterguard as an outwork in bastion fortification, citing historical sources.
  • Identify counterguards on historical plans and surviving sites.

Moral aspects Filled

  • Surviving outworks are fragile heritage that is easily lost to development and erosion.
  • Fortifications recall sieges and deaths that deserve respectful description.

Who is affected

  • Heritage bodies
  • Visitors to historic sites
  • Local communities

Owners Filled

Steward

The owner of the fortification site; heritage authorities where it is protected.

Master systems

  • National heritage and monument registers
