You could walk past this tiny medieval Sephardic synagogue without realizing it is here; the door is not well marked. This prayer house was built at the end of the 14th century and was excavated accidentally in 1964; no one knew it was here. What was found were Jewish decorations on the walls of a chapel from the 17th century. One picture shows a bow pointing to heaven with statements from Hanna's prayer: "The bows of the mighty men are broken, and they that stumbled are girded with strength." Another is a Star of David with Aaron's blessing: "The LORD bless thee, and keep thee: The LORD make his face shine upon thee, and be gracious unto thee," as translated in the King James Bible. In the entry chamber there is a medieval grave with headstones on display demonstrating the life and history of the early Jews in the area. The English-speaking caretaker will give you a free informal tour; he is more than pleased to have visitors. You can pretty much see the whole place from the entry; consider your admission fee a contribution to the museum.
