Templo y Ex Convento de San Nicolás Tolentino

Built around 1613, the Templo de San Nicolás Tolentino is among the oldest surviving religious structures in San Cristóbal de las Casas, predating the elaborate baroque facades of the Templo de Santo Domingo and the city's cathedral by several decades. The church served the barrio of San Nicolás, one of the outlying indigenous and mixed-caste neighbourhoods that grew up beyond the walled Spanish centre of colonial Ciudad Real, and its plain adobe-and-tile construction, with a single unadorned bell gable rather than a carved stone facade, reflects both the modest resources available to a peripheral parish and the deliberate architectural hierarchy the Spanish colonial administration imposed between the central Spanish parishes and those serving indigenous barrios. The interior retains its original single-nave layout and a simple wooden altarpiece, with later additions limited to devotional side altars added by the parish community over the eighteenth and nineteenth centuries; there is no elaborate gilded retablo comparable to Santo Domingo's. INAH and the Diocese of San Cristóbal have carried out periodic structural conservation on the adobe walls and roof timbers, most visibly after seismic activity in the region, but the church has not been substantially rebuilt or modernised, leaving its exterior close to its seventeenth-century appearance. It remains an active parish church rather than a museum piece, with regular Mass and community devotions continuing inside, which limits access during services but keeps the building in continuous use rather than preserved purely as a monument. Architecturally, the church is a useful counterpoint to San Cristóbal's grander religious buildings, illustrating how colonial urban planning used parish architecture to mark social and ethnic boundaries within the town as clearly as any physical wall.
