On February 7, 2023, its remains were discovered inside of the old hospital of La Misercordia due to maintenance work that had been ordered by the city council in 2021.
[3] Following the expulsion of Jews, it was converted into the Hospital of Mercy, which was run by the Catholic Church, and was established to help foundlings.
[4] The Christian community had maintained the original architecture of the building until the 17th century, when the roof was raised and two side naves were added into the hall of prayer, and the extant wall paintings are all dated to no earlier than the 18th century.
Excavations began on November 18, 2021, and were led by archaeologist Miguel Ángel de Dios Pérez and architect Antonio Jaramillo.
