Hundreds of Families Face Forced Eviction Near NATO Munitions Depot in Portugal

The Portugal Ministry of Defense has formally escalated a decades-old safety crisis involving illegal housing built dangerously close to a NATO ammunition storage facility, asking the nation's top legal authority whether it can forcibly expropriate land and relocate hundreds of families living in what officials describe as a potential catastrophe zone.

Why This Matters

• Safety risk: Residents in Sesimbra and Seixal municipalities live near a high-capacity explosives depot that handles NATO munitions daily

• Legal limbo: Over 50 years of illegal construction have created communities without proper infrastructure, electricity, or water access

• Potential displacement: The government is exploring public interest expropriations and mandatory demolitions that could affect hundreds of households

• NATO obligations: Portugal's international defense commitments require secure perimeters around strategic military installations

Half a Century of Uncontrolled Development

Defense Minister Nuno Melo submitted his formal inquiry to the Attorney General's Advisory Council on April 2, seeking legal clarity on how Portugal can address settlements that have developed inside the military protection zone surrounding the Lisbon NATO Munitions Depot in Fernão Ferro. The ministry's statement acknowledged the challenge: the restricted zone has seen extensive construction over decades, with the Portuguese Navy unable to enforce compliance alone.

The military servitude area was established in 1959 precisely to prevent residential development adjacent to warehouses storing explosives. What began as occasional structures gradually transformed into permanent dwellings. The Portuguese Navy, which oversees the depot, has initiated enforcement actions but has acknowledged lacking the statutory authority to manage civilian relocations—a responsibility that falls to municipal governments under Portuguese law.

Strategic Infrastructure Meets Environmental Protection

The legal situation is complicated by overlapping jurisdictions. The depot straddles the border of Sesimbra and Seixal municipalities in Setúbal district, roughly 30 kilometers south of Lisbon. It also sits within a sensitive ecological area: the Fernão Ferro/Lagoa de Albufeira Special Conservation Area, protected under both the National Ecological Reserve (REN) and the EU's Natura 2000 network.

Minister Melo's submission to the Attorney General poses critical questions about how administrative proceedings should be conducted. Specifically, he seeks guidance on whether the state can declare public utility status for expropriation of the military servitude zone and how enforcement powers should be coordinated among military authorities, municipal councils, and environmental regulators responsible for REN and Natura 2000 compliance.

The Ministry of Defense underscored that the facility represents "military infrastructure of elevated strategic relevance" within Portugal's national defense framework and its international NATO commitments. The depot is catalogued in NATO's official inventory of critical installations, a designation that obligates Portugal to maintain adequate territorial security conditions.

What This Means for Residents

For the estimated hundreds of families living within the restricted perimeter, the government's legal inquiry signals that displacement may be considered. Residents currently occupy homes with precarious or nonexistent access to municipal water, sewage systems, and regulated electricity. Some have lived there for extended periods despite the technical illegality of their dwellings.

The Seixal Municipal Council has noted the prolonged inaction by the Defense Ministry and Navy in addressing the situation. The municipality's master plan formally recognizes the military servitude as an existing administrative restriction and public utility constraint.

The Expropriation Pathway

Portugal's legal framework permits government expropriation of private property when public interest demands, provided authorities demonstrate the measure is adequate, necessary, and proportionate. The Defense Minister has authority to order embargoes or demolitions of illegal construction within military servitude zones, but executing those orders against occupied residences raises constitutional and humanitarian questions—hence the Attorney General consultation.

The Defense Ministry statement emphasized the government is "committed to adopting necessary and legal procedures to resolve this question," language suggesting readiness to pursue formal channels once legal guidance is received.

Environmental and Security Layers

Any action within the Natura 2000 zone requires compliance with EU biodiversity directives. The REN designation prohibits most forms of development to protect water resources, soil stability, and ecological corridors. The military servitude and ecological protections theoretically reinforce each other, yet enforcement gaps have allowed residential encroachment that violates both frameworks.

Melo's inquiry specifically asks how military, municipal, and environmental authorities should coordinate enforcement, acknowledging that jurisdictional confusion has complicated the situation.

A Test of Political Will

Resolving the Fernão Ferro situation demands not only financial resources but considerable political will to implement what will undoubtedly be a difficult process. The alternative—tolerating residential communities adjacent to a high-tonnage munitions facility with daily explosives handling—creates liability exposure that no government can indefinitely ignore.

The Attorney General's opinion, expected in the coming months, will likely shape whether Portugal pursues aggressive expropriation and demolition or opts for alternative strategies. Either approach will test the Portugal Cabinet's capacity to balance security obligations, environmental compliance, legal integrity, and social considerations.

For now, hundreds of families remain in an uncertain situation, their futures dependent on a legal interpretation that will determine how Portugal addresses this long-standing land-use conflict adjacent to one of NATO's critical installations on the Iberian Peninsula.
