Andorra Restores Sant Serni de Nagol Church with €55,000 Investment

The Andorran Department of Cultural Heritage has completed restoration work on the Sant Serni de Nagol church in Sant Julià de Lòria, with a total investment exceeding €55,000. The project, finished ahead of a recent UNESCO evaluation visit, restored the site's original features and atmosphere, including its 11th-century consecration and surviving in-situ mural paintings—the oldest known in Andorra.

Crews removed the wooden parquet flooring added in 2017 from the nave, apse, and 18th-century porch, revealing the underlying natural stone pavement. A specialist team repaired damaged areas with hydraulic lime mortar, secured loose slabs, and applied matching colored sands for seamless integration, said restorer Mireia Tarrés. The apse and nave walls, previously whitewashed, now feature a subtle greyish lime patina aligned with the murals depicting saints, a bishop, and angels on the triumphal arch.

A key highlight is the late-Gothic altarpiece of Sant Serni, originally from the 16th century. Previously facing the rear wall, it has been cleaned, conserved, and returned to its north-wall position over preserved stone supports. Tarrés noted its modest construction—wooden structure with limited funding for decoration, including the central saint figure, a Calvary scene above, Christ and Mary monograms, a sun and moon, and plain panels—crafted by a skilled painter evident in the faces. Two other altarpieces, one Baroque and one of Sant Martí, are in storage awaiting further work.

Additional upgrades include reopening a side window sealed in the 1976 restoration to boost natural light, a relocated and discreet electrical panel above the choir loft, enhanced targeted lighting, new CCTV cameras, and intrusion detection. The choir staircase and liturgical furnishings like pews, a cross, and lantern received conservation treatment. Facade and entry graffiti were documented; notable examples include a 1399 debt note by the priest, a 1577 altarpiece sketch, a warrior helmet, a boat silhouette, and World War II-era inscriptions—one signed "Landemaine" on 4 December 1941 and 26 April 1945, another dated 4-12-1944 and 1-1-1945—shared with historian Pau Chica.

Coordinator Joan Reguant said the UNESCO committee, visiting last week for Andorra's Coprincipat origins candidacy, left particularly impressed by Sant Serni. Department director Isabel de la Parte praised the intervention for recapturing the church's authentic spirit and spaciousness without overpowering its historic essence. The changes ensure the temple's enduring protection.
