Santa Eulalia Basilica
In Merida, the Santa Eulalia Basilica is an ancient Roman basilica whose ruins lie beneath the current 18th-century church.
Santa Eulalia Basilica was named after a 13-year-old girl who was martyred by being burned at the stake during Emperor Diocletian's Christian persecutions. She is said to be buried nearby, according to mythology.
The crypt of the Santa Eulalia Basilica is particularly remarkable since it contains Roman mausoleums, a tomb sealed with mosaics, and graves from the Visigoth period sealed with marble, which spans 20 centuries of Merida's history.
