Also in the Costa de Prata region, in the city of Tomar, an ancient 15th century Jewish synagogue and mikveh, one of the two surviving monuments of medieval Jewish heritage, can be found. The synagogue has become a national museum and features historic remains of medieval Portugese communities. In 1993 a Yom Kippur service was held at the synagogue because of the large number of Jewish tourists.
One of the now Jewish nieghbors was afraid the synagogue would be destroyed and petitioned for it to be a historic site. WhIle he is not Jewish he singlehandedly revived and redid the building. He learned hebrew and takes care of everything
