Yet for Weidenhofer it's simply the way it's done: "A restoration isn't successful unless other people can't tell that it has been restored." She says that the first job in restoring old buildings is to protect them from further damage, the second is to find the cause of the damage and fix it, and the third is to teach so that others can protect the buildings in the future.
登霍夫卻覺得自然：「只有別人看不出曾有人來修過，才算成功。」她說文物保存的第一要件是保護古物不再受侵害，第二才是找出病徵做修護，第三步則是傳授日後保存之道。
