Fort Marie-Christine

The Fort Marie-Christine is a Sardinian fort of the Esseillon barrier at Aussois, Savoie. The site carries French historic-monument protection (classé 27 juin 1983, national register notice PA00118188).

When is it open? All year, every day, with no published closing day. No opening hours are published either, and we do not invent any.

What does it cost? Nothing. Access is free, and the source says so explicitly — we do not infer it from an absent price list.

No official source says anything about accessibility here: neither accessible nor inaccessible — unknown. Animals are not accepted.

This page is built on official sources and nothing else: the site's manager, the commune, the park, the tourist office, the national bathing-water register. Where two of them contradict each other, both are given and the gap is flagged — we do not choose for you. Where they are silent, the field stays empty rather than guessed.

A covered or heritage site: as much a bad-weather outing as a fine-weather one. Check the weekly closing day before you go — that is where visits are lost.
