Wait — I must be careful: the source says "dans le département de CALVADOS" and "dont l'histoire remonte." with truncated sentence (no date). I must not add info. Also "Calvados" as department name in Russian: "департамент Кальвадос" is standard. Keep the truncation faithfully: "история которого восходит" with no completion — that's the preservation of the source's incompleteness. Use ellipsis? The source ends "remonte." with a period. Better: "восходит." Hmm, Russian needs an object; leaving "восходит." is awkward but faithful. I'll write "история которого восходит." to mirror it.
Also "château" -> "замок" but source says "site castral" -> "замковый объект" / "замковое сооружение". "Domaine de Beauregard" — Russian standard form? Not established; transliterate "Домен Борегар" or keep "Домен Бовуар" (I wrote Бовуар, which is Beauvoir, not Beauregard). Correct: Beauregard = Борегар. Fix.
Also the "Calvados" department: "Кальвадос" is the established form.
