Origin and history

The church of Saint-Gilles (originally dedicated to Saint-Laurent) of Mont-d'Astarac, built in the 15th century, illustrates the religious architecture of the late Middle Ages. Built in soft molass stone on pebbles foundations, it is distinguished by a unique nave divided into three spans, flanked by side vaulted chapels of warheads. Its pentagonal bedside, supported by radiant buttresses, houses 15th century frescoes depicting biblical scenes (the tree of Jesse, the Supper, the Passion of Christ). These murals, rare for the period, highlight the artistic importance of the building in the region.

The church is part of a homogeneous architectural family with the neighbouring churches of Seissan, Chêlan, Castelnau and Monléon, sharing common characteristics: use of local materials (molasse, pebbles, brick), pentagonal or square bedside, broad nave bordered with chapels, and lighting by curved windows. The polygonal bell tower, coupled with the nave, saw its high parts rebuilt in 1840, while the arch on cross-walls of warheads was only added between 1850 and 1854. The current porch, dated 1853, nevertheless incorporates re-used medieval sculptures, probably from the original porch.

Subsequent changes include the addition of a sacristy in 1886 (right-hand fall of the nave) and the replacement of stained glass windows in 1882, although the overall structure retains its late Gothic identity. Classified as a Historical Monument in 1975, the church bears witness to the architectural and liturgical evolutions of the region, while preserving exceptional medieval elements such as its frescoes and carved vault keys. Its plan, marked by an asymmetry of the chapels (two on the right, one on the left), may reflect different topographic constraints or construction phases.

The historical context of its construction coincides with a period of economic and religious renewal in southwestern France, marked by the reconstruction of buildings after the Hundred Years' War. The churches of the Upper Valley of Gers, like Saint-Gilles, served as places of community gathering and demonstration of power for local lords or bourgeois enriched by commerce (wine, pastel). Their decoration, though modest, was designed to educate the faithful through painted Bible accounts in an area where illiteracy was widespread.

The use of molasses, a local sedimentary stone easy to cut but fragile, explains some of the degradations observed today. The restoration campaigns of the 19th and 20th centuries (voûts, bell tower, porch) met structural needs, but also a desire for liturgical modernization (addition of sacristy) or aesthetic (negothic windows). The inscription in the Historical Monuments in 1975 allowed to preserve this heritage, now owned by the commune of Mont-d'Astarac.
