罗yon城堡 Wait — the name "Royon" should be kept in the established form. In Chinese, is there an established form for Château de Royon? Not known to me as established; I must not invent a name. Transliterating a Latin-script name isn't required; the rule says use established form when it exists, otherwise transliteration applies for non-Latin scripts. For a Latin-script target like Chinese, Chinese is non-Latin, so transliterate in standard manner: Royon → 鲁瓦永 (Lu Wayong). Rather than invent, transliteration is acceptable. Use 鲁瓦永城堡. Segment 2: "situé, dans le département de PAS-DE-CALAIS" — keep "PAS-DE-CALAIS" as is (names of departments; could be kept in Latin since it's a proper name; translate to 加来海峡省 is the established Chinese form). Established form exists: Pas-de-Calais = 加来海峡省. Use that. "dont l'histoire remonte." — incomplete sentence in source; preserve incompleteness: "其历史可追溯至" would add content? It's truncated; keep as "其历史可追溯至。"? That adds a period-like ending but no info. Better to render literally with a trailing cut: "其历史可以追溯到" without object—mirrors source's incompleteness. Source ends "remonte." — translate "其历史可追溯至" then 。 Fine.

Le château d'origine a été détruit en 1944 pendant la Seconde Guerre mondiale puis reconstruit vers 1960. Avant sa destruction, l'édifice était de style Louis XV. Son parc est inventorié à la base Mérimée (IA62001081).
