The Santuario de Nuestra Senora de Schoenstatt is a small Catholic shrine built in 1943 in the Parque del Colegio de Hermanas. It adds a later layer to the town's Central European religious landscape.
It is a quiet stop rather than a major monument, but it fits Nueva Helvecia well: imported traditions, local devotion, and a townscape that keeps its immigrant memory close to the surface.
