The square tower, located in the center of the medieval village of Rosans, dates from the 12th century. The walls are made of diamond-cut stone blocks, four meters thick, and each face looks at one of the four cardinal points, so that when three of its sides are in the shade, it marks the hour of noon. This tower, wrongly called "Tour Sarrasine" is not an example of the Moorish architecture in the South of France. The building is listed as a historical monument since 1932.
