Synagogen in Copenhagen

You're standing on Krystalgade, at number 12, outside the Great Synagogue of Copenhagen. This is home to the city's Orthodox Jewish congregation, and the building has stood here since 1833. Take a look at the façade. It's strikingly plain. Architect Gustav Friedrich Hetsch went for a Neoclassical style, with clean lines and very little decoration. From out here, nothing gives away what's waiting inside.
