"Café Terrace at night, Place du Forum, Arles", is kept at the Kroller-Muller Museum in Otterlo, in the Netherlands. In February 1888, Van Gogh moves to Arles. Here he is deeply inspired by the Provencal countryside and nature, which push him to create a large series of paintings. Seduced by the French nightlife, he begins attending nightclubs, including the Café de Place du Forum, which, one evening in September, he decides to portray with a trestle placed in the middle of the street. The beauty of the picture is given by the contrast between: the warm colours that make up the Café and the cold ones, which instead are filling the facades of buildings and everything that is in the distance. The strong contrast between the artificial lights of the atmosphere, and the natural light of the stars in the sky, perfectly represented by the masterly use of warm and cold colours, gives the work a strong sense of realism. In order to paint the night, Van Gogh uses blue, yellow, violet and green, altered shades that represent, according to the artist, the only way to get away from the conventional image of dark and whitish light. The meaning of the painting can only be grasped by analysing Van Gogh's thought and mentality: the intense activity of the Café and human activities in the night stand out, contrasting the icy darkness of a city that sleeps instead and without this small building with the tables and the chattering people would be empty and unlit. Van Gogh paints the places of Arles on several occasions. In a letter addressed to his sister Wilhelmina, the artist reveals all his pleasure in portraying the Café de Place du Forum: "Cela m'amuse énormément de peindre la nuit sur la place". The subject is painted without preparatory drawing, in the immediacy of the vision: "autrefois on dessinait et peignait le jour d'après le dessin. Mais moi je m'en trouve bien de peindre la chose immédiatement".
