Wait — I must not add or remove info. The source says "dont l'histoire remonte." (truncated, no date). I should preserve that incomplete phrasing faithfully, not invent a date. Use an equivalent Russian construction that doesn't invent: "история которого восходит" would be incomplete too. Better: "история которого уходит корнями" ... still incomplete. Keep ellipsis-like ending with a period as source does: "...история которого восходит." Hmm, source has "remonte." followed by period. Russian: "история которого восходит." is odd but faithful. Maybe "история которого уходит в глубь веков"? That adds meaning. Keep faithful: "восходит."
Also "site castral" → "замковый объект" or "замковое укрепление"? "Site castral" = castle site. Use "замковый комплекс"? Keep "замковое место" maybe. "Édifice" → "постройка". "Patrimoine castral" → "замковое наследие".
Name: "manoir des Champeaux" — Russian established form? Keep "манuар де Шампо" transliteration. Department "Calvados" is in Russian "Кальвадос" — fine.
