Chiesa di S. Eustachio

This is a church built like a fortress: a sturdy rectangle of stone and brick, ending in a polygonal apse. The main hall and apse are covered by barrel vaults of camorcanna, a lightweight reed-and-plaster technique. A square chapel dedicated to the saint is crowned with a brick dome, laid in herringbone pattern, a deft piece of masonry. The sacristy is a simple rectangle with a wooden ceiling. Outside, the bell tower rises, capped by a conical brick spire. Below ground, a rectangular cellar is also barrel-vaulted. The whole building is roofed with simple pitched slopes, supported by rafters, while the central nave uses exposed wooden trusses. It is a practical, defensive sort of piety, with each element built for endurance rather than display. The materials are honest, the forms clear; the place feels less like a sanctuary and more like a stronghold of faith.
