San Felipe Fortress
Colombia
San Felipe Fortress is strongest on Defensibility 8/10 — Purpose-built surviving fortress fabric on a rocky crag provides robust passive defense, elevation and internal depth. Urban exposure and continuing conservation needs keep it below exceptional classes.. Its clearest scored constraint is Isolation 0/10 — The fortress is embedded in the major living city of Cartagena and directly overlooks urban approaches, meeting the evidenced lowest isolation anchor..

Field assessment
At a glance
Bottom Line
For the fixed 20-person Base boundary, the most important endurance constraint is Resource Security 1/10 — Current restored building fabric does not establish protected independent potable water, durable food production or survival-critical energy within the fortress after Cartagena systems fail..
Biggest Trade-off
The central trade-off is the catalogue's strongest evidenced dimension, Defensibility at 8/10, against its weakest evidenced dimension, Isolation at 0/10.
Most Likely Failure
The evaluation leaves this material failure condition unresolved: Protected current potable water inside the fortress boundary is not established.
Score rationale
Why it scores this way
Defensibility · 8/10
Purpose-built surviving fortress fabric on a rocky crag provides robust passive defense, elevation and internal depth. Urban exposure and continuing conservation needs keep it below exceptional classes.
Advantages
- Positive credit is limited to what supports the Defensibility score of 8/10; the component rationale is: Purpose-built surviving fortress fabric on a rocky crag provides robust passive defense, elevation and internal depth. Urban exposure and continuing conservation needs keep it below exceptional classes.
Limitations
- Do not infer additional Defensibility capability outside the fixed Base boundary or beyond the recorded evidence.
Isolation · 0/10
The fortress is embedded in the major living city of Cartagena and directly overlooks urban approaches, meeting the evidenced lowest isolation anchor.
Advantages
- Positive credit is limited to what supports the Isolation score of 0/10; the component rationale is: The fortress is embedded in the major living city of Cartagena and directly overlooks urban approaches, meeting the evidenced lowest isolation anchor.
Limitations
- Do not infer additional Isolation capability outside the fixed Base boundary or beyond the recorded evidence.
Sustainability · 3/10
Substantial enclosed and restored fortress spaces can provide shelter, but current twenty-person sleeping, sanitation, food-preparation and ventilation support are not established as a long-duration residential system.
Advantages
- Positive credit is limited to what supports the Sustainability score of 3/10; the component rationale is: Substantial enclosed and restored fortress spaces can provide shelter, but current twenty-person sleeping, sanitation, food-preparation and ventilation support are not established as a long-duration residential system.
Limitations
- Do not infer additional Sustainability capability outside the fixed Base boundary or beyond the recorded evidence.
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 — Purpose-built surviving fortress fabric on a rocky crag provides robust passive defense, elevation and internal depth. Urban exposure and continuing conservation needs keep it below exceptional classes..
Risks
- The weaker current condition in this horizon is Exposure Control 7/10 — Rocky elevation and purpose-built approach control provide strong sightlines and channelled entry, while dense surrounding urban fabric creates many nearby pressure sources.; 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 4/10 — The fortress has substantial physical volume for twenty people, but present residential sanitation and service throughput are not evidenced well enough to claim comfortable larger-community headroom..
Risks
- The weaker current condition in this horizon is Sustainability 3/10 — Substantial enclosed and restored fortress spaces can provide shelter, but current twenty-person sleeping, sanitation, food-preparation and ventilation support are not established as a long-duration residential system.; 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 4/10 — Heavy masonry retains passive value, but current protection work explicitly requires preventive, corrective and waterproofing interventions, so capability degrades materially without maintenance..
Risks
- The weaker current condition in this horizon is Resource Security 1/10 — Current restored building fabric does not establish protected independent potable water, durable food production or survival-critical energy within the fortress after Cartagena systems fail.; 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 Defensibility 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: Current restored building fabric does not establish protected independent potable water, durable food production or survival-critical energy within the fortress after Cartagena systems fail.
Strengths
- One of the strongest scored dimensions is Defensibility 8/10 — Purpose-built surviving fortress fabric on a rocky crag provides robust passive defense, elevation and internal depth. Urban exposure and continuing conservation needs keep it below exceptional classes..
- One of the strongest scored dimensions is Exposure Control 7/10 — Rocky elevation and purpose-built approach control provide strong sightlines and channelled entry, while dense surrounding urban fabric creates many nearby pressure sources..
- One of the strongest scored dimensions is Maintenance Resilience 4/10 — Heavy masonry retains passive value, but current protection work explicitly requires preventive, corrective and waterproofing interventions, so capability degrades materially without maintenance..
Weaknesses
- One of the weakest scored dimensions is Isolation 0/10 — The fortress is embedded in the major living city of Cartagena and directly overlooks urban approaches, meeting the evidenced lowest isolation anchor..
- One of the weakest scored dimensions is Resource Security 1/10 — Current restored building fabric does not establish protected independent potable water, durable food production or survival-critical energy within the fortress after Cartagena systems fail..
- One of the weakest scored dimensions is Sustainability 3/10 — Substantial enclosed and restored fortress spaces can provide shelter, but current twenty-person sleeping, sanitation, food-preparation and ventilation support are not established as a long-duration residential system..
Assumptions / constraints
- Only assets inside the recorded Core Base and immediate operating boundary are credited; excluded surroundings and unproven future access remain outside the score.
