Originally only the section between Lastadie and Poggenpfuhl was built up on one side and traversed by a covered drainage ditch, which is why it was called "uff der Trumme." The section between Poggenpfuhl and the Mottlau formed a nameless fire lane until the beginning of the 19th century, separating the Dielenmarkt (the later parade ground) from the Mastenfeld. The part beyond the Aschbrücke extending to the Thornsche Brücke was called Brückengasse (Bridge Lane) from 1643, and Thornsche Brückengasse from 1805. This name, shortened to Thornsche Gasse, then encompassed the entire lane from about 1817 onward. The designation Thornsche Brücke derives from the Vistula barges from Thorn that moored here; previously it was called Knüppelbrücke (Log Bridge). The Aschbrücke is named after the adjacent new Aschhof (ash yard), which was relocated here in 1449 after the old Aschhof at the opposite end of the Speicherinsel had burned down. The lane is also listed on some maps as Thornscher Weg. After the war, this lane was extended to the northwest beyond Fleischergasse to Wiebenwall. It was intended to serve as a traffic axis for the Lower Town and the Suburb.
