The synagogue at the Folkingestraat in Groningen was built in 1906 and is known to have oriental features in its windows and arcades. This photo shows the space on the first floor where the women took their seat behind a balustrade, after entering the synagogue through a side entrance.
During WWII the Germans used the synagogue as a storage for confiscated radios; the metal that the radios contained was then used in the German war industry. After the war the synagogue fell into decay, however in the late 1970s it was decided to restore the building.
After walking by the synagogue so many times without stopping, I spontaneously decided to go in one afternoon last month. It was worth it!
