Nagysimonyi was one of the centers of the Jewish community of Kemenes region in the 1700s. The Simonyi community was founded by 18 families who resettled from Germany. Their synagogue was built in the 19th century and had to be rebuilt after a fire in 1892. The unused building was demolished in 1953. Today their cemetery is separated from the settlement by the Szombathely-Celldömölk railway line. The cemetery is surrounded by a wall and has beautiful tombstones from the 19th century. Here is the tomb of the scholar rabbi Simon “Sabtaj” Weisz, who died in 1944. It is notable that it was this cemetery in which, in 1877, the county’s first Jewish ceremony in Hungarian language was held.
