"Jews in Daroca" Daroca Travelogue by FruitLover

During the period of Muslim rule the Jewish quarter of Daroca was situated on the slope of Mt. San Jorge at the eastern approach to the valley, with the Jewish cemetery nearby.

The Daroca community flourished during the 13th century. For example, the arrest of Jews on the Sabbath and Jewish holidays was prohibited.
Accusations were rife in 1321 that the Jews had poisoned the wells.
Regulations concerning the institution and observance of the Jewith OATH in Daroca were introduced by Alfonso IV in 1330; the deponent was required to take the oath at the entrance to the synagogue, holding the Torah scroll, in the presence of three Christian witnesses only.
[Jewish Oath was a special form of oath, accompanied by certain ceremonies and often intentionally humiliating or dangerous, that Jews were required to take in European courts of law until the 20th century].

On 1414 the townsfolk of Daroca threatened to expel the Jews unless they adopted Christianity, all the Jews en masse were arrested. A number of the Jews let themselves down from the city walls by rope at night and made their escape. Of the 40 Jewish families who had been living in Daroca, only ten persons then remained, all in prison.

The state of affairs evidently imroved, however, and in 1458 the limits of the Jewish quarter were defined by John II in order to prevent Jews living alongside Christians.

Jewish property in Daroca was looted after the issue of the edict of expultion of the Jews from Spain in 1492. The synagogue and hospital had been sold along with other Jewish communal property.
