« Here in Schaffhausen, work is done. »— Official motto of the city of Schaffhausen, (Old German)
Your mission begins on Fronwagplatz, the historic central square of Schaffhausen, surrounded by medieval half-timbered buildings dating from the 15th-16th centuries. This convergence point of pedestrian streets like Vordergasse and Hintergasse, the heart of the Altstadt historic district, has been the scene of markets and public events since the Middle Ages. Immediately nearby, the Fronwagturm, a watchtower built in 1557 as part of the city's fortifications, offers a first clue about the defenses that failed to protect the city from the skies in 1944. You explore this 0.5-hectare area, looking for the marks of the past and the echoes of the error that struck this Swiss medieval city.
The Fronwagturm, a fortified tower 22 meters high with its bulbous roof typical of 16th-century Swiss fortifications, was historically used as a watchtower and prison until the 19th century. Restored in 1990, it symbolizes Schaffhausen's defenses against Swabian raids in the Middle Ages. As you head towards the Münster Schaffhausen, you pass the former Romanesque abbey founded in 1080, transformed into a parish church after the Reformation in 1524. Its main nave, dating from 1100-1150, and its 12th-century Romanesque cloister, bear witness to a thousand-year history. This is where Saint Wiborada († 926), Switzerland's first saint, canonized in 1047, rests, whose tomb survived the trials of time.
Your journey then takes you to the Rathaus Schaffhausen, the town hall built between 1568 and 1570 in the late Renaissance style. Its facade adorned with 72 painted coats of arms and its 30-meter main tower, with a clock from 1589, served as the seat of the municipal council since its construction. The historical frescoes in its inner courtyard, depicting the emperors of the Holy Roman Empire, offer a striking contrast to the destructions of 1944. Descending towards the Rhein, you cross a strategic site for medieval trade between the Alps and the North Sea. The river, which flows through Schaffhausen for about 1.5 km, was the site of historical river navigation since the 13th century, with a wooden bridge replaced by a metal bridge in 1861.
The Bahnhof Schaffhausen, a railway station inaugurated in 1857 by the Rhine Valley Railway line, is a crucial hub. Its neo-Renaissance main building and 400-meter platforms were a key junction between Switzerland and Germany, electrified in 1927. Restored in 2015, it testifies to Schaffhausen's importance as a crossroads. On your way to the Munot, a circular Renaissance fort built between 1564 and 1572 on the order of the city council, you admire this fortification inspired by Italian Renaissance defenses, designed by Otto von Gammach. Its 152-step spiral staircase leads to a viewpoint, offering a view of the city, its monuments, and the proximity of the Rhine Falls.
Your exploration concludes with Herrenacker, a historic public square of 1.2 hectares, used for markets and festivals since the 14th century. Surrounded by 17th-18th century patrician houses, with a fountain dating from 1780, it was a place for political speeches and gatherings during the Swiss Reformation in the 1520s. Returning towards Vordergasse, you conclude your investigation into the traces of the 1944 error. This interactive visit of Schaffhausen, highlighting keywords such as UNESCO World Heritage candidacy Altstadt Schaffhausen and Historic Monument Munot 1564, will have allowed you to discover the history of Schaffhausen and its heritage, while exploring the monuments and the impact of these events on this Swiss medieval city.
