Nożyk Synagogue in Warsaw

You're standing at the Nożyk Synagogue, on Twarda Street in the centre of Warsaw. Take a good look at the façade first. Architect Karol Kozłowski went for a Romanesque Revival style, with round arches and a touch of Byzantine flair here and there. The same Kozłowski also designed the hall of the Warsaw Philharmonic. The building itself is a simple rectangle.
