There are four plazas around the cathedral, all with food vendors if you’re up for a tamale, taco or torta (sandwich). The largest public space is Plaza de la Liberación to the east.
This square, drawn up in 1952, is often used for free concerts and is known locally as the “Plaza de las Dos Copas”, for its two fountains shaped like wine glasses.
There’s a larger than life-sized monument to Miguel Hidalgo y Costilla symbolising his abolition of slavery in 1810. Afterwards you can drop by Plaza Guadalajara, which has an underground shopping center, and Plaza de Armas, where there’s a French 19th-century wrought iron bandstand used in the past for rabble-rousing political speeches.
