Carcassonne
France
Carcassonne is strongest on Population Capacity 9/10 — A complete inhabited fortified town containing houses, streets, cathedral, castle, extensive current visitor/commercial infrastructure and a currently authorised hotel sleeping capacity of 144 offers exceptional functional headroom beyond twenty people.. Its clearest scored constraint is Isolation 2/10 — The Cité is physically distinct but embedded within modern Carcassonne and ordinary road/rail connectivity. Walls create local separation, not meaningful geographic removal from a substantial surrounding population source..

Bottom Line
For the fixed 20-person Base boundary, the most important endurance constraint is Resource Security 3/10 — The Cité is an inhabited urban compound with current year-round food-service, sanitation and residential infrastructure, and its history includes substantial dedicated potable-water works. Those facts establish useful starting resources, but no authoritative evidence establishes a protected current water source/storage/treatment pathway independent of municipal systems, durable internal food production or survival-critical energy independence. The result therefore fits useful starting resources with major dependencies..
Biggest Trade-off
The central trade-off is the catalogue's strongest evidenced dimension, Population Capacity at 9/10, against its weakest evidenced dimension, Isolation at 2/10.
Most Likely Failure
The evaluation leaves this material failure condition unresolved: The Cité has current water-dependent residential, sanitation and food-service infrastructure and documented historic potable-water works, but current independent potable source, protected storage, treatment and outage continuity are not established. Resource Security 3 credits the evidenced starting-resource position while retaining this limitation for explicit package adjudication.
Score rationale
Why it scores this way
Defensibility · 8/10
A massive double wall, dozens of towers, barbicans, moat geometry, castle and elaborate gated entrances provide very strong defense in depth and useful fallback. The scale and inhabited urban interior impose more twenty-person burden than the exceptional 9-class sites.
Advantages
- Positive credit is limited to what supports the Defensibility score of 8/10; the component rationale is: A massive double wall, dozens of towers, barbicans, moat geometry, castle and elaborate gated entrances provide very strong defense in depth and useful fallback. The scale and inhabited urban interior impose more twenty-person burden than the exceptional 9-class sites.
Limitations
- Do not infer additional Defensibility capability outside the fixed Base boundary or beyond the recorded evidence.
Isolation · 2/10
The Cité is physically distinct but embedded within modern Carcassonne and ordinary road/rail connectivity. Walls create local separation, not meaningful geographic removal from a substantial surrounding population source.
Advantages
- Positive credit is limited to what supports the Isolation score of 2/10; the component rationale is: The Cité is physically distinct but embedded within modern Carcassonne and ordinary road/rail connectivity. Walls create local separation, not meaningful geographic removal from a substantial surrounding population source.
Limitations
- Do not infer additional Isolation capability outside the fixed Base boundary or beyond the recorded evidence.
Sustainability · 7/10
An inhabited internal urban fabric with houses, streets, toilets, year-round food-service spaces and current hotel sleeping capacity well above twenty provides strong adaptable shelter, sanitation and daily-life infrastructure. Municipal utility dependence remains a material limitation.

Survival horizons
How survival changes over time
First 7 days: current defence/contact profile
First 7 Days
This horizon does not invent future upgrades or resupply. It carries the current evaluated conditions forward and keeps unknown future capability uncredited.
Positive factors
- The stronger current condition in this horizon is Defensibility 8/10 — A massive double wall, dozens of towers, barbicans, moat geometry, castle and elaborate gated entrances provide very strong defense in depth and useful fallback. The scale and inhabited urban interior impose more twenty-person burden than the exceptional 9-class sites..
Risks
- The weaker current condition in this horizon is Defensibility 8/10 — A massive double wall, dozens of towers, barbicans, moat geometry, castle and elaborate gated entrances provide very strong defense in depth and useful fallback. The scale and inhabited urban interior impose more twenty-person burden than the exceptional 9-class sites.; no better future state is assumed.
First 100 days: current habitat/capacity profile
First 100 Days
This horizon does not invent future upgrades or resupply. It carries the current evaluated conditions forward and keeps unknown future capability uncredited.
Positive factors
- The stronger current condition in this horizon is Population Capacity 9/10 — A complete inhabited fortified town containing houses, streets, cathedral, castle, extensive current visitor/commercial infrastructure and a currently authorised hotel sleeping capacity of 144 offers exceptional functional headroom beyond twenty people..
Risks
- The weaker current condition in this horizon is Sustainability 7/10 — An inhabited internal urban fabric with houses, streets, toilets, year-round food-service spaces and current hotel sleeping capacity well above twenty provides strong adaptable shelter, sanitation and daily-life infrastructure. Municipal utility dependence remains a material limitation.; no better future state is assumed.
Long term: current resource/maintenance profile
Long Term
This horizon does not invent future upgrades or resupply. It carries the current evaluated conditions forward and keeps unknown future capability uncredited.
Positive factors
- The stronger current condition in this horizon is Maintenance Resilience 5/10 — Stone fortifications and dense masonry buildings retain substantial passive value, while modern sanitation, utilities and occupied-building safety depend on municipal systems and ongoing conservation. Capability degrades in stages rather than collapsing immediately..
Risks
- The weaker current condition in this horizon is Resource Security 3/10 — The Cité is an inhabited urban compound with current year-round food-service, sanitation and residential infrastructure, and its history includes substantial dedicated potable-water works. Those facts establish useful starting resources, but no authoritative evidence establishes a protected current water source/storage/treatment pathway independent of municipal systems, durable internal food production or survival-critical energy independence. The result therefore fits useful starting resources with major dependencies.; no better future state is assumed.
Tactical assessment
Practical Reality
Reality Check
Scores apply only to the defined Base and exactly 20 capable adults. Unknown, excluded or external assets are not credited as hidden capability.
Best Use
Within the evaluated boundary, treat Population Capacity as the primary operational strength; do not promote that score into capabilities the evidence does not establish.
Key Risk
Resource Security is the key evidenced long-duration risk: The Cité is an inhabited urban compound with current year-round food-service, sanitation and residential infrastructure, and its history includes substantial dedicated potable-water works. Those facts establish useful starting resources, but no authoritative evidence establishes a protected current water source/storage/treatment pathway independent of municipal systems, durable internal food production or survival-critical energy independence. The result therefore fits useful starting resources with major dependencies.
Strengths
- One of the strongest scored dimensions is Population Capacity 9/10 — A complete inhabited fortified town containing houses, streets, cathedral, castle, extensive current visitor/commercial infrastructure and a currently authorised hotel sleeping capacity of 144 offers exceptional functional headroom beyond twenty people..
- One of the strongest scored dimensions is Defensibility 8/10 — A massive double wall, dozens of towers, barbicans, moat geometry, castle and elaborate gated entrances provide very strong defense in depth and useful fallback. The scale and inhabited urban interior impose more twenty-person burden than the exceptional 9-class sites..
- One of the strongest scored dimensions is Exposure Control 8/10 — Double walls, barbicans, two elaborate principal entrances and tower observation strongly channel and reveal final approaches. The very large perimeter and dense built interior create some monitoring complexity, keeping it below the rarest classes..
Weaknesses
- One of the weakest scored dimensions is Isolation 2/10 — The Cité is physically distinct but embedded within modern Carcassonne and ordinary road/rail connectivity. Walls create local separation, not meaningful geographic removal from a substantial surrounding population source..
