State fortification
Works built and garrisoned by a state rather than held by a lord: artillery forts, bastion and star forts, citadels, coastal batteries, and the fortified systems of the gunpowder age onward.
Criterion
A fortification commissioned, owned or garrisoned by a state, polity or municipality as a military installation, where no private lordly residence is the organising purpose. Typically post-1500 and designed against artillery, but the test is tenure and military purpose, not date.
Includes
- Bastion and star forts; Vauban-system citadels and fortified towns
- Coastal artillery forts, Martello and signal towers
- Nineteenth and twentieth-century defensive works, including WWI/WWII
- Urban citadels and town defences held communally
Excludes
- Lordly castles later garrisoned by a state — the original purpose governs
- Field works and temporary siege works
Closure: enumerable
Closable in principle — states keep records of their own works — but much weaker in practice than the two bands above, because military estates are documented by defence ministries rather than heritage registers and the twentieth-century material is barely surveyed anywhere.

Assessed records
Structures somebody applied this criterion to, with the reasoning.
- Neuf-Brisach — yes: A Vauban-system fortified town built by the French crown from 1698, octagonal bastioned enceinte, purely military in commission and garrison. Inscribed by UNESCO within the Fortifications of Vauban serial property.
- Elmina Castle — yes: Built and garrisoned by the Portuguese crown as a fortified trading post and later held by the Dutch and British states. State commission and military purpose, with no private lordly residence organising it.
- Crac des Chevaliers — contested: The Hospitallers functioned as a quasi-sovereign military corporation, so the work is arguably state-like in commission and garrison while remaining formally non-royal. The same ambiguity that makes the residence verdict contested makes this one contested.
