Capilla de Tegua, Colonial religious building in Río Cuarto, Argentina.

Capilla de Tegua is a small chapel in the paraje of Tegua, Río Cuarto Department, Córdoba, near National Route 36 between Elena and Alcira Gigena. Its restored façade has a wall with an arcade and a bell gable (espadaña) holding the replaced bell. Inside are a wooden altarpiece and altar, both restored, and the narthex wall was partly rebuilt.

Founded in 1696, this building is one of the southernmost religious seats established by Spanish colonists in Córdoba Province during their territorial expansion. Its construction marked an important moment when colonial authorities sought to strengthen their presence in the southern regions.

The chapel serves as a gathering place where the local community continues to practice their Catholic faith and celebrate traditional religious occasions. The interior conveys how people have worshipped in this space for centuries, maintaining rituals that remain central to regional identity.

The building sits readily accessible along National Route 36 between Elena and Alcira Gigena, with modern amenities including solar power and updated facilities. The location makes it straightforward to visit and explore without requiring special arrangements or difficult navigation.

The chapel stood between the postas of Santa Bárbara and Corral de Barrancas on the Carril de los Chilenos, the road linking Córdoba with San Luis, Mendoza and Chile during the Viceroyalty and early Independence. The Posta de Tegua stood near the chapel and the Arroyo Tegua in the 19th century.
