The Over-Restored Parish Church
A parish church in central France, listed since 1912, has a 12th-century nave with carved capitals. Its west facade was rebuilt in 1880 by a diocesan architect who replaced the portal tympanum with a copy and scraped the interior walls back to bare stone. The parish now wants to repaint the interior 'as it would have looked in the Middle Ages' and install heating. A conservation report notes surviving 15th-century wall paintings under 19th-century limewash in two bays; the scraped surfaces have no original polychromy. The regional conservation authority can fund either paint analysis (EUR 18,000) or a heating system (EUR 40,000), not both this year. The priest argues that the 1880 restoration is itself part of the building's history and should not be undone, while a parishioner group wants a bright medieval interior for winter services.
1. Should the parish repaint the interior in a reconstructed medieval scheme? Advise, distinguishing evidence from conjecture and addressing reversibility.

No permanent medievalising repaint. The evidence base is two bays of 15th-century painting under limewash plus an 1880 scrape that removed original polychromy. There is no surviving scheme for the nave, no colour sample from the 12th-century finish, and no documentary description. A full repaint would invent a medieval appearance and fix an interpretation in irreversible paint.
Distinguish conservation from interpretation. First fund paint analysis to locate and characterise the surviving paintings; conserve those areas and the 1880 surfaces as historic fabric. If the parish wants colour, use reversible interpretation: discreet panels, digital projection for services, or a temporary limewash tint that can be removed after testing. Avoid covering the two painted bays.
Address the 1880 work. The priest is right that the 1880 restoration is part of the building's history; do not strip it to chase an imagined 12th-century look. The conservation principles are minimum intervention, reversibility and honest disclosure. A faculty or heritage consent should require mock-ups and a maintenance plan. The parishioner group's wish for brightness can be met with lighting and heating, not speculative paint.
2. The parish must choose between funding paint analysis (EUR 18,000) and a new heating system (EUR 40,000). Which should the conservation authority prioritise, and why?

Prioritise heating only with environmental control, not as a simple either/or. The active risk is condensation and winter damp on the 15th-century paintings and stone. Paint analysis (EUR 18,000) is valuable but does not stop deterioration; heating (EUR 40,000) can, if it is specified with humidity control and monitoring. However, badly designed heating can dry and crack wall paintings, so the authority should fund a monitored heating scheme with conditions: relative-humidity limits, data loggers and a post-installation review. Defer the full paint analysis to next year and use a small diagnostic sample now. If the paintings are actively flaking, reverse the priority and fund analysis plus emergency consolidation first. The decision should follow risk to fabric, not the parish's aesthetic preference.
