Abstract
In this review paper, I describe the fine structure of a well-developed sunspot, as it appears when observed with a spatial resolution of 0″3 or 0″25.1 do not restrict myself to describing morphological properties, because I also want to show how the small scale features are associated with the velocity and magnetic field patterns. This is now possible thanks to recent spectrographic and magnetographic observations obtained at the Swedish Telescope at La Palma (Canary Islands) with a resolution close to 0″3. These high-resolution observations of the intensity, velocity and magnetic structure of sunspots are very helpful in discussing the validity of more elaborate models.
