What it is Filled
A defensive work built outside the main enceinte of a fortress to strengthen a front, cover a gate or occupy ground that would otherwise shelter an attacker, including ravelins, hornworks with two demi-bastions, crownworks with a central bastion and two half-bastions, lunettes and redoubts; outworks occur in earlier fortifications as well as in bastion fortification of the sixteenth to nineteenth centuries and survive at many fortress sites.
Why it exists Filled
Let an agent identify kinds of outwork and their roles in fortifications across historical periods, including bastion fortification, relay surviving examples and references, and explain the terminology of fortification for heritage and historical use.
Distinguishing features Filled
- Outworks stand outside the main defensive wall.
- Many bastion-era outworks have angular geometry, while earlier forms vary.
- Named types are distinguished by their plans.
- Surviving outworks form part of fortress heritage.
What robots and AI may and may not do Filled
Must not
- Confuse types of outwork, such as calling a crownwork a hornwork, in records or interpretation.
- Dig, metal-detect or remove material from an outwork without archaeological consent.
- Use terms for bastion outworks to describe earlier or unrelated defences.
- Direct visitors onto unstable ramparts or ditch edges of an outwork.
Only with a human decision
- Any excavation, clearance or restoration of an outwork.
May
- Identify and describe an outwork, naming its type such as ravelin, hornwork or lunette.
- Map the surviving outworks of a fortress from surveys and historical plans.
- Report erosion, vegetation or encroachment on an outwork to its custodian.
Moral aspects Filled
- Outworks are often the least protected part of a fortress and are lost to building and farming.
- Fortifications can be presented in ways that glorify past violence rather than explain it.
Who is affected
- Heritage custodians
- Visitors to fortresses
- Landowners near fortresses
Owners Filled
Steward
The owner or heritage body that holds the fortress; heritage registers record protected sites.
