The Horber market square, first mentioned in 1277, has the shape of a street market that widened at the apex of Marktstraße and rejuvenated at the confluence of Wintergasse. The city hall is mentioned for the first time in the 1420 written down Horber city law. All houses on the market were rebuilt after the big city fire in 1725 on the fire debris of the medieval Upper Town, where the 1733 started town hall only forty years after the devastating fire put on the top floor. In 1860, the city acquired a neighboring building, in which one set up the guard for the two night watchmen in addition to the detention center. However, the new council and the adjacent guardhouse were only by their painting 1925/27 a special gem on the upper market square. On the gable sides of the two houses, the local painter and sculptor Wilhelm Klink designed the so-called Horber picture book, which has a lot to tell about the history of the Neckarstadt and its important sons with its coat of arms displays and portrait medallions. The flower-crowned Horber Stadtwappen strive for a Biedermeier wedding and a craftsman train, in which numerous portraits can be found from the former population. Above the scene of the crucifixion, below the gable-top, with the triangular halo and the Hebrew 'Jahve', one sees an old Christian symbol for the Trinity. The funny sayings of the then Latin school teacher Dr. Stefan Lösch wrote, and the inscriptions right, faithfulness, love as well as diligence always remind the Horber of the most important bourgeois virtues. The Horber Bilderbuch was restored in 1998 and 2000 by the Kultur- und Museumsverein.
