The synagogue in Kurkliai is similar in style to the 18th century Historicist architecture of the now-destroyed Polish wooden synagogues.
It is almost square in plan, of one and a half-storeys and it has a small corner tower with a peaked roof that accommodates stairs that lead to the women’s gallery. It has a plain façade with some Moorish styling of the windows which are narrow and high and crowned with a peaked triangle. It is this style of fenestration that reflects the Historicist style. The interior now consists of a single space with all original partitions lost.
