A walking party around downtown's distinctive "callejones" (narrow streets or alleys) complete with live music and a donkey loaded with free Mezcal. Usually everybody is welcomed to join and most likely you won't be the only tourist joining the entourage. Callejoneadas typically begin from the Plaza de Armas.

The square beside the Cathedral, interesting murals inside the government buildings, such as the Palacio de Gobierno.
Catedral Basílica de la Asunción de María de Zacatecas
One of the most beautiful examples of Churrigueresque arquitecture in Mexico. It is an elaborately carved red-stone (cantera) structure that was built between 1730 and 1760. It is flanked by two towers with an exuberant ornamentation and has a notable facade that was richly sculpted but its once decorated interior was looted during the civil wars of the 19th and 20th centuries. Its coupula was reconstructed in 1836 and imitates that one of the church of Nuestra Señora de Loreto in Mexico City.
Parroquia de Santo Domingo
Built by the Jesuits between 1746 and 1749, this church has a beautiful Baroque facade. Splendid gold wood-carved altarpieces, all of them churrigueresque, as well as 18th-century Francisco Antonio Vallejo paintings that represent scenes of The Passion, can be found inside.
Located next to the "Santo Domingo" church, it houses a colonial-era library and a large eclectic collection of European, African, American, and Mexican art.
Impressive facade.
Casa de Moneda
A museum located across the street from San Augustín with exhibitions all about Zacatecas, notable residents and its long history. Of note is a large section of exhibits, crafts, and other artifacts belonging to the Huichol culture, whose members still maintain a pre-Columbian lifestyle in the mountains between Zacatecas and Nayarit.
