Boulevard Montmartre at Night displays the busy Parisian boulevard, but at night right after a downpour. The work gave the Danish-French artist the opportunity of studying the new electric street lamps' effect as they are aligned at the street as well as the orange glow of those gas lights seen in the windows. He tried to represent the various effects that artificial lights have in different colours: bluish and pale as well as intense.
Abstract vertical shapes in the painting represent the crowds moving under the trees and beyond the shops. On one side of this road, there is a series of carriages that are lined and the lights are on, waiting for the exit of the guests who were at the show that took place at the Moulin Rouge, which is located just around the corner. The sky is dark and misty, and the clouds are seen hanging in the air. But stars that are seen in the sky (the small sketches of white), show that the clouds are going to pass soon.
