The Agoudas Hakehilos Synagogue is often referred to as the Pavee Synagogue as it is located on rue Pavee in the IV arrondissement of Paris. It is one of the very few synagogues, or for that matter houses of prayer of any denomination, designed in the Art Nouveau (Jugenstil) style.
In the early part of the 20th century this synagogue was commissioned by the Agoudas Hakehilos (אֲגֻדָּת־הַקְּהִלּוֹת, Union of the Communities), society composed of Orthodox Jews of primarily Russian origin. At that time Hector Guimard, who designed the Paris Metro and other magnificent Art Nouveau projects, was selected as the architect. Guimard, whose wife was Jewish, took on the challenge of designing the synagogue for the narrow lot. It is the only religious building ever designed by Guimard who was known for his Art Nouveau designs. The furnishings, including light fixtures, benches, door handles and other fittings were all created by Guimard.
According to Wikipedia "On the evening of Yom Kippur in 1941, the building was dynamited along with six other Parisian synagogues. It was subsequently restored and was registered as a monument historique by the French authorities on June 4, 1989."
