This modern Basilica is designed by the same architect who designed the Museo Nacional of Antropologia. Inside this Basilica there is room for 10.000 believers. The interior of this new Basilica is very modern. Personally I do prefer the interior of the Old Basilica as it was something special. The new Basilica was consecrated in 1976. To prevent jamming near the high altar, from where you can see the coat of Juan Diego, they have constructed a conveyer band, so that the pilgrims slowly pass by the holy Coat. On this coat you can see the portrait of the Virgin of Guadelupe. On the painting (pict 4) you can see Juan Diego with his coat and on the coat reflects the portrait of The Virgin. Note that the Virgin has a dark face.
There are two explanations why over here they call The Holy Virgin Guadelupe.
The first version is that the Bishop who did not speak Nahuatl asked Juan Diego if the Virgin had told him her name. Juan Diego answered, "Yes, her name is Santa Maria Coatlaxopeuh (Holy Maria who trampled a snake)." Coatlaxopeuh was corrupted by the Bishop to Guadelupe.
More likely the Virgin's name was imported by the Spanish. Most of the Conquistadores were coming from Extramadura, where this Virgin of Guadelupe already was known since 1322, in a village named after her.
