One of the best kept secrets of the capital of Seville is hidden underground, specifically in the crypt of the Iglesia de la Anunciación (Church of the Annunciation), although it can be accessed through the patio of the University School of Fine Arts, the building next to the temple.
The Nuestra Señora del Carmen Church was founded in the 18th century on the site of 16th-century Shrine to Cristo de la Sangre. A few Gothic-Mudejar elements from the Shrine still can be seen.
The Marquises of Estepa used the temple’s crypt as their pantheon for many centuries.
This church was initially a chapel and family pantheon built by the 2nd Count of Olivares. His son, Gaspar, succeeded in having it elevated to the status of collegiate church through a papal decree. This allowed the church to operate independently from the Archdiocese of Seville.
