As a fan of Art Nouveau architecture, I had to stop by the Agoudas Hakehilos Synagogue, which was designed by Hector Guimard around 1913. Guimard is perhaps most well known for his Metropolitain entrances at select Metro stops as well as his Castel Berenger in Paris. Situated on a narrow street, snug among other buildings of similar height, we saw only the exterior of this Jewish synagogue building. Activity and light from within indicated it is still in use. There are five stories, curved white stone facade, two-story entrance, tall skinny windows, tablets top center. It has survived a fire and attempted WWII bombing. But it needs some TLC. Nonetheless, the Art Nouveau elements are of sufficient interest to warrant a visit for an architecture fan. Note the building's cornerstone showing the architect's name and the building's date.
