I heard that there is also a Star of David from the Roman period inscribed on one of the stones that build this synagogue but haven't seen its picture yet:
The synagogue was built in 1873, on the ruins of an ancient synagogue.

Sabbioneta Print

On the first page of Maimonides' book, "moreh nevuchim" (guide to the perplexed) in Sabbioneta print from 1553 there's a Star of David in the leaves of the tree in the bottom center. The printer, Tobias ben Eliezer Foa, used it as a personal printers' signature on a few of his Hebrew books.
