« Queen of Death, come and free me from all evil. »— Anonymous inscription, Fresco inscription of the Totentanz at Basler Münster, circa 1440
Your quest begins on Münsterplatz, the forecourt of the imposing Basler Münster. This Gothic cathedral, whose construction began in 1019 and was completed in the 14th century with its two 71-meter towers, was the scene of the collapse of the Princes' Chapel during the 1356 Basel earthquake. It was this tragic event that inspired the famous local Dance Macabre. You will walk in the footsteps of medieval processions related to the Totentanz, imagining the 40 figures painted in 1440 by Manuel Deutsch in the Galleries of the Dead. The tomb of Emperor Henry III, buried in 1056, and his son Henry IV, buried in 1106, recall the long history of this ISOS historical monument, one of the most important in the historic city of Basel-Stadt.
Continue your itinerary towards Peterskirche, Basel's oldest Romanesque church, founded around 1100. Its bell tower, rebuilt in 1508, overlooks 14th-century medieval frescoes inside, whose eschatological motifs recall the themes of death that obsess you. This place served as a burial site for the cathedral canons until the secularization of 1529, a major turning point for the city of Basel. By exploring this site, you will perceive how medieval spirituality mingled with existential anxieties, a constant in Basel's history.
Your path then leads you to the Spalentor, one of the three fortified city gates still standing. Built between 1398 and 1400, this 23-meter-high gate, flanked by three cylindrical towers, is the last of Basel's 26 medieval gates. Restored between 1870 and 1872, it still bears the inscription 'SPALENTOR 1400' in Old German. This remnant of Basel's defense system offers you a perspective on the city in the 15th century, a time when the Totentanz was a palpable artistic and spiritual reality. The gate is a key entry point for understanding Basel's heritage, a city whose UNESCO World Heritage candidacy is planned for 2025.
Crossing the city, you will reach the Rathaus Basel, the town hall built between 1504 and 1521 by Hans Jacob and Hans Heinrich von Tiefen. Its Renaissance facade, adorned with 84 painted windows, is classified as a Swiss historical monument. This building was the seat of the Council of Thirteen from 1521, and it was here that crucial decisions on the Reformation were made by Oecolampadius in 1529. This site, central to understanding Basel's history and its political evolution, shows the city's transition from the Middle Ages to the Renaissance, a period rich in upheavals and artistic creation, like your own work.
Your journey concludes by ascending the medieval alley of Totengässlein, 1.2 meters narrow, an intact remnant of the 14th-century tanners' quarter. Its overhanging houses dating from 1400-1450 take you back to the time when you were painting. This Basel treasure hunt will have allowed you to decipher the warnings of the Dance Macabre, from Münsterplatz to Rheinsprung, passing through Predigerkirche and Peterskirche. You leave with a deep understanding of Basel's motto, 'Künftigkeit durch Einigkeit', and the certainty that art can transcend the fear of death, a timeless message from the historic city of Basel-Stadt.
