The Basílica de Santa María de Guadalupe (Basilica of Our Lady of Guadalupe) is an important religious site in Mexico City. The first shrine built to honor the Virgin Mary of Guadalupe was erected in 1531 on Tepeyac hill, but the first basilica dedicated to the Virgin Mary was not built until 1695. However, nearly 300 years' worth of construction and environmental damage threatened the integrity of the basilica, so a new basilica was built on the same plaza in the 1970s.

Today, the complex has many features including the basilica, the ancient church, a gift shop filled with religious items, a museum and a library. Visitors extolled the basilica, saying that it is a must-see whether you are Catholic or not. Though Mass is held frequently, reviewers noted that the layout of the buildings helps visitors avoid interrupting worship. In addition, past travelers said a variety of tours were available from Mexico City (some of which included Teotihuacan) and said it was a great way to have a fully-informed experience. The basilica is also often featured as a stop on hop-on, hop-off bus tours. 

The basilica is open every day, though the hours at each individual site within the complex vary. Admission to the museum is 10 pesos (about 50 cents), while the rest of the complex is free (though you may wish to make a cash donation). You can access the basilica from the La Villa-Basílica subway station on the red line (metro line 6) or via the Deportivo 18 de Marzo station on the olive green line (metro line 3).
