The archaeological remains from the Jewish quarter of Lorca are located in the precinct of the castle, covering an area of about 5575m 2 .All of them have been fully documented and recorded. Twelve houses have been excavated so far, and together with the synagogue, they form this Jewish quarter.

The urban planning is adapted to the natural slope of the ground. This was already modified because of the construction of ancient Islamic buildings, designed both for residential and defensive purposes. The archaeological remains are arranged in four terraces from the wall line that separates the Alcázar (the fortress) from the quarter itself. The irregular street layout is due to this disposition in terraces, having as a central point the synagogue. It has also been documented the existence of narrow streets to connect these terraces.

The structure of the houses is simple, with a floor plan rectangular in shape and different areas subdivided into smaller rooms and also raised bedrooms. Continuous wall benches are usually found in this kind of buildings as well as kitchens, larders and jar stands.

As for the crockery, it used to be made by local potters, even though there have also been found some other pieces from the Levantine area and Granada. These lasts were characterised by their decorations in gold or blue colour. The nine-branched candelabras or Hanukiah are considered as the most important archaeological finds. Each Jewish family had a Hanukiah , which was set up at a prominent window so that passers-by should see it during Hanukkah . This festival was instituted by the rabbis according to the Talmud , starting on the 25 th day of the Kislev (which may occur by the end of December). It is observed for eight days, by the kindling of the lights of a nine-branched candelabrum, one light each night of the holiday, progressing to eight to the final night. The extra light called a shamash was used to lit the others.

There is no doubt that the synagogue was the main building in the Jewish quarter. Built in a downward slope, the floor level was below the ground level, and thus it was obtained a greater height inside but not outside, obeying the laws at that time.

Two openings, one each side of the patio, gave access to the building, whereas an independent outside opening gave access to the women gallery. Inside the prayer hall, aniche, which contained the Torah rolls, is still preserved. It is named Aron or Ark and it was decorated with plasterworks in Gothic style. Some pieces of the skirting board from the bimah (a large raised platform where the Torah was read) have also been conserved. Along the perimeter of the prayer hall there used to be a continuous wall bench where men seated. Like in many other synagogues, women had a private area for worshiping called matroneum , in this case a gallery located above the entrance hall. It had an independent access.

The synagogue was lit up with glass oil lamps hanging from the ceiling along the prayer hall. Twenty of these lamps have been recovered after a meticulous research and restoration work.
