ABSTRACT Wall paintings are physically indivisible from the built heritage, which makes their conservation difficult. Conservation measures focus on stabilising paintings and slowing deterioration, while preserving significance and authenticity. Achieving these aims is complicated. The altered states in which paintings usually survive – due to events, exposure, neglect, misguided restorations, and other causes – do not always require stabilisation efforts, but their authenticity and significance may be severely undermined. At the same time, interventions to re-establish these values may expose paintings to physical risk. Balancing these dilemmas in practice requires constant evaluation of risks, objectives and outcomes. Conservation cannot be concerned with the attainment of conspicuous visual results while deterioration issues remain unaddressed. Neither can problems that impair the historic integrity and meaning of wall paintings be ignored. For over 30 years, the Courtauld Institute of Art, London, UK, has played a central role in educating conservators to meet the challenges of the discipline, through a well-established curriculum and a wide range of international projects in the field. From this perspective, this paper examines current challenges in wall painting conservation.

保护壁画的挑战：30 年展望

摘要 壁画与建筑遗产在物理上是不可分割的，这使得它们的保护变得困难。保护措施的重点是稳定绘画和减缓恶化，同时保持意义和真实性。实现这些目标是复杂的。由于事件、曝光、疏忽、误导性修复和其他原因，绘画通常存在的改变状态并不总是需要稳定工作，但它们的真实性和意义可能会受到严重破坏。与此同时，重建这些价值观的干预措施可能会使绘画面临身体风险。在实践中平衡这些困境需要不断评估风险、目标和结果。保护不能关注获得显眼的视觉效果，而退化问题仍未得到解决。也不能忽视损害壁画历史完整性和意义的问题。30 多年来，英国伦敦考陶尔德艺术学院通过完善的课程和该领域的广泛国际项目，在教育保护人员应对学科挑战方面发挥了核心作用。从这个角度，本文探讨了当前壁画保护的挑战。
