The second neighborhood is the "Barrio de San Marcos", which has its roots in the early 17th century as an indigenous settlement on the outskirts of the then-village of Aguascalientes. Between 1628 and 1688, some communal land was allocated to the community, but the indigenous people still worked on Spanish-owned farms and produced goods to sell in Aguascalientes. Meanwhile, they organized the construction of a simple hospital and a chapel. This original chapel was replaced by the current "Templo de San Marcos" completed on December 15, 1763; this church is the spiritual headquarters of the "Feria Nacional de San Marcos".
