A small square with a romantic and kind of gloomy name "Place des Six Montagnes Noires" (Six Black Mountains) is located in the very center of Colmar. Everything here is small, though, and is situated in the center, which can be walked around in half an hour according to the map. But, as a rule, tourists stay in Colmar for a day or even two.

It is convenient to choose Six Black Mountains Square as a starting point for different routes, whether it be the quarters of Fishermen or Tanners, "Little Venice" or the Champ de Mars (Field of Mars). The square got its name from the hotel, which was located on it from the 14th to the 19th century. The reason why the owner chose to call it Six Black Mountains is unknown. But it is known that many legendary personalities stayed there: Field Marshal Gustav Horn (hero of the Thirty Years' War who strengthened France in Europe), Marshal Turenne (who deprived Spain of domination in Europe, forcing it to sign the Peace of the Pyrenees) and even Cardinal Jules Mazarin. The hotel burned down at the end of the 19th century, but the original name remained.

There is a monument in the center of the square, as is no doubt right and proper. In this case, the first hero of Colmar, Johann Roesselmann, is mounted on a bronze pedestal. Born in Tanners' Quarter, he was lowborn but intelligent. He became the city mayor even without proper education. The episcopate decided to overthrow him and replace the civil administration of the city with an ecclesiastical one. Roesselmann was sent into exile but managed to return to the city by a trick (in a barrel of wine) and brought the fight to the bishop's troops. It cost him his life. According to the idea of the author, the monument is also a fountain decorated with wrought fish.

The square is surrounded by half-timbered houses. The French often use the word "colombage" when they talk about this style. The Bartholdi Lyceum is adjacent to the square. Once, there was a monastery where the Jesuits taught theology, philosophy, and Latin. However, in the middle of the 18th century, this order fell from grace (they refused to renounce obedience to the pope and swear an oath to the king of France). Therefore, their activities were suspended in this country, and the church school became a secular royal college.
