Short answer. Article 677 of the Civil Code prohibits any construction or planting near fortified places or fortresses unless it satisfies the conditions found in special laws, ordinances, and regulations that specifically govern such areas. The rule replaces the Code's usual neighbor-distance framework with whatever military or security regulations apply to the fortified site.
What the law says
No constructions can be built or plantings made near fortified places or fortresses without compliance with the conditions required in special laws, ordinances, and regulations relating thereto.

Why the ordinary distance rules do not apply
Most of this Title of the Civil Code fixes specific distances or conditions neighbors must observe when building, planting, or opening windows near an adjoining property, protecting light, privacy, and structural safety between private owners. Article 677 breaks from that pattern for land near a fortified place or fortress: the concern there is not a neighbor's privacy but the defense and security function of the installation itself. That difference in purpose is what justifies routing compliance through defense-related regulation instead of the Code's usual formulas.
Which rules actually control construction near a fort
The article does not set its own distance or design limit. Instead it defers entirely to whatever special laws, ordinances, and regulations the competent authorities have issued for fortified places or fortresses. That can include military reservation rules, zoning restrictions tied to a defense installation, or clearances issued by the agency responsible for the site. Because those external rules can change independently of the Civil Code, a builder cannot rely on Article 677 alone as proof of compliance — it only points to where the real requirements live, and ignoring them can expose the builder to penalties under the special law itself, not just a private easement dispute.
What counts as a fortified place
The Civil Code does not define 'fortified places or fortresses' beyond the ordinary sense of a fortified military installation such as a fort, garrison, or defense post. Because the provision was written broadly, the safest approach for anyone planning work near a site with a visible military or defense function is to treat it as covered unless a specific regulation says otherwise.
Practical steps before you build or plant nearby
Anyone planning to build a structure or put in plantings near a fortified area should first identify which agency issued the special regulations for that site and confirm what conditions apply before starting work. Skipping this step does not just risk a dispute with a neighbor; it can mean noncompliance with rules meant to protect a defense installation, which carries its own consequences. Where the location is unclear or borderline, confirming with the relevant authority in writing before construction begins avoids having to explain noncompliance after the fact.
How this fits with the rest of the easement rules
This article sits among the Civil Code provisions on distances and intermediate works for easements, which otherwise focus on light, view, drainage, and similar concerns between adjoining private landowners. Article 677 is the exception in that group built around a public security interest rather than a private one, which is why compliance is measured against special legislation instead of a fixed number of meters.
