The Old Synagogue appears documented for the first time in 1412, a year in which it was granted by the guardians of King Juan II to the convent of St. Mary of Mercy to compensate for the plots which this community had handed over for the segregations of the Jews. The guardians of Juan II specified that the monks had to set up at the building of the old synagogue a hospital to shelter the poor but there is no record that they did so. At present nothing remains of the Old Synagogue; the plot taken up by the convent of Mercy was used in the 19th century to open a square opposite St. Andrew´s Church. Alongside the Old Synagogue at the current Merced (Mercy) Square there stood one of the two religious schools of Segovia. In 1412 it starts belonging to convent of St. Mary of Mercy, as well as the synagogue. The synagogue has since been transformed into the church of the Corpus Christi convent.
