The synagogue has a simple tripartite façade with a central body in red brick and stone slabs with two doors (one of which under a portico leads directly to the women's gallery) and two small windows with an ornamental reference to the Star of David.

The interior has a single room with the raised balcony of the women's gallery overlooking the entrance.

[4] The Italian-style marble tabernacle containing the holy ark with the books of the Torah was a gift in 1934 from the Jews of Trieste to the Fiuman confreres (until then it adorned the Schola grande in Piazza delle Scuole israelitiche in Trieste).

The temple remained standing, because during the Nazi occupation it was used as an ammunition depot, while the large synagogue in Rijeka was destroyed on January 25, 1944.

After the war, the small Orthodox synagogue was thus able to house the few surviving Rijeka Jews of that which until a few years earlier was a thriving community of over 2,000 members.
