San Martín: A Gothic Apse over a Romanesque Church
The parish church of San Martín in a Castilian village is a protected monument. Its nave, built around 1180, has a pointed barrel vault, carved capitals with foliate and geometric motifs, and a southern portal with scalloped archivolts. In 1520 a Gothic apse with rib vaulting and a large gilded retablo was added; the retablo completely covers the eastern wall. During emergency repairs after a roof leak, conservators removing 20th-century whitewash from the apse discovered a 14th-century mural of the Last Judgment with a weighing of souls, visible only in a 60 cm strip beside the retablo. The parish has raised €90,000 and wants the retablo restored and kept in place; the heritage office wants the mural uncovered and studied. The building is still used for weekly Mass and two annual processions. Work must finish within eight months to prevent further water damage.
1. Reconstruct the building's chronology and identify the stylistic affiliations of the nave and apse. What uncertainties remain?
Read the worked answer
The nave is late Romanesque, not Gothic. A pointed barrel vault can appear in Cistercian-influenced buildings, and the scalloped portal and foliate capitals belong to Romanesque carving. The 1520 apse with rib vaulting is Gothic in structure but already Renaissance in date; date it by the retablo contract, the vault ribs, and mortar. The mural is probably 14th century and therefore earlier than the apse, which means it was covered when the Gothic east end was built. Uncertainties remain: whether the pointed vault is original or a later reinforcement; whether the mural was painted before or after the apse; and whether the retablo has been moved. Resolve these with dendrochronology of roof timbers, mortar analysis, and study of the apse wall sequence.
2. Recommend a conservation and display strategy that respects both the retablo and the mural within the budget and liturgical constraints.

Set a sequence. First stop water ingress and stabilize the climate, because €90,000 will not cover everything. Document the retablo fully before touching it. Expose and consolidate the mural in situ; remove whitewash only under controlled conditions and after test patches. Do not detach the retablo permanently. A reversible solution is to open a narrow, well-lit viewing bay beside it and use a high-quality digital facsimile or mirror to show the whole mural. If the retablo must be moved, record and store it in a controlled space and plan reinstallation. Keep Mass and processions by scheduling work around them. Spend first on roof, drainage, and environmental control; seek extra funds for the retablo. Explain the trade-offs to the parish.
3. How should the parish and heritage office decide? Set out decision criteria and the risks of each option.
Read the worked answer
Use a decision matrix: significance of the mural versus the retablo, integrity, reversibility, cost, liturgical needs, legal protection, and public benefit. The mural is earlier and rarer, but the retablo is the parish's devotional focus and has its own value. Minimum intervention should prevail: stabilize both, interpret the layers, and avoid a winner-takes-all restoration. Consult the heritage office, parish, conservators, and art historians; record dissent. Set review points after tests. If the budget forces a choice, protect the structure and the mural's edges first, because water damage is active; the retablo can be stabilized and restored later. Publish the reasoning so the decision is accountable.
