The old castle square is now named after Friedrich Schiller (1759-1805) and has an imposing statue of the poet and dramatist in its centre (executed by Danish sculptor and friend to the poet, Bertel Thorwaldsen). Schiller’s position was previously filled by a fountain, the water for which was housed in the water tower concealed as the Hermes column behind the Alte Kanzlei, which used to be the castle kitchens. This and other squares host the various markets of the city.
