The synagogue in Góra Kalwaria, located at 10/12 Pijarska Street, was built in 1903 as a private prayer house for the Alter family, adjacent to the court of the tzaddik Alter. The brick synagogue, constructed on a rectangular plan, has retained distinctive architectural features to this day, such as the cast-iron columns of the women's gallery and a stylized Star of David in the circular window above the main entrance. It is also worth noting the unique matzo oven located in the attic, which reflects the cultural and religious traditions of the Jewish community. Unfortunately, the synagogue also has a tragic history; during World War II, it was the site of mass executions of Jews, underscoring its significance as a symbol of suffering and persecution. After the war, the building was transferred to the Jewish community of Warsaw, and in 2016, after a two-year legal process, Roman Giertych helped the Jewish community regain ownership of the synagogue, highlighting its historical and cultural value. Today, the synagogue is an important part of local heritage and stands as a testament to the history of Jews in Poland.
