This is an analysis of how an immigrant cultural group expresses its cultural identity through sacred architecture. Sacred architecture has the ability to transcend its purely religious role and reflects the attributes of an individual cultural group. Immigrant cultural identity illustrates the process of acculturation once immigration occurs. The duality of what is retained from a groups previous homeland and what is assimilated from a new environment manifests in the physical attributes of cultural identity such as architecture. This research focuses on the German speaking immigrants of Texas whose cultural migration to Texas began in the early 1830s and whose cultural identity remains today through their sacred architecture.
