Aguascalientes is one of central Mexico's easier cities to underestimate. It is tidy, prosperous, and less theatrical than nearby Zacatecas, but the centre has a strong identity built around printmaking, death imagery, hot-spring history, and the country's biggest fair.
The city's best cultural thread starts with José Guadalupe Posada, the Aguascalientes-born illustrator whose calaveras shaped modern Mexican visual culture. The Museo José Guadalupe Posada anchors that story in the old Encino neighbourhood, while the National Museum of Death expands it into a broader, stranger, very Mexican conversation about mortality.
The historic centre is compact enough to wander. Plaza de la Patria is the formal heart, Templo de San Antonio is the architectural showpiece, and Jardin de San Marcos becomes the city's social stage during the Feria Nacional de San Marcos. Aguascalientes is not a first-trip-to-Mexico essential, but if you are already in the Bajio or moving between Zacatecas and Guadalajara, it gives a good day.
