Templo y Exconvento de San Diego

The Templo y Exconvento de San Diego stands on Rivero y Gutierrez in the Zona Centro of Aguascalientes, Mexico, immediately opposite El Parian and a short walk from the Plaza de la Patria. Its history begins in 1640, when Barefoot Carmelites established a religious house on the northern edge of what was then a small settlement on the road to Zacatecas. The Carmelites left, and in 1661 the complex passed to the Franciscans, whose order gave it the dedication to San Diego de Alcala that it still carries. The temple itself was completed in 1682, making it one of the oldest surviving religious buildings in the state and a rare seventeenth-century survival in a city whose skyline is otherwise dominated by eighteenth- and nineteenth-century work. Architecturally the church is sober rather than exuberant: a single nave under a barrel vault, a modest stone portal with paired pilasters, and a bell tower added in later campaigns. Interior decoration reflects successive reworkings, with neoclassical altars replacing earlier baroque retablos during the nineteenth century, a pattern common across central Mexico after the Bourbon reforms. The adjoining cloister had a longer secular afterlife than the church. Following the nineteenth-century Reform Laws that stripped religious orders of their property, the former convent was put to public use and became the region's first agricultural school, training students in the irrigation and viticulture that shaped the Aguascalientes valley. In 1973 the building was one of the founding properties of the Universidad Autonoma de Aguascalientes, and parts of the complex have since served university and cultural functions, with the arcaded patio restored and reused rather than reconstructed. Visitors today encounter a working parish church rather than a museum: there are no ticketed galleries, and the interpretation available on site is limited to plaques. The interest lies in reading the fabric itself, the seventeenth-century shell, the later altars, and the conventual patio that records the shift from monastic to educational use. Entry is free, and the temple's position facing El Parian makes it a natural stop on a walking circuit of the historic centre.
