Originally, only the section between Lastadie and Poggenpfuhl was built up on one side and traversed by a covered drainage canal (hence called uff der Trumme). The section between Poggenpfuhl and the Mottlau formed a nameless fire lane separating Mastenfeld and Dielenmarkt. The section between Aschbrücke and Thornsche Brücke was first called — from 1643 — Brückengasse (Bridge Lane), then — from 1805 — Thornsche Brückengasse. This name, shortened to Thornsche Gasse, encompassed the entire lane from 1817. The designation Thornsche Brücke is said to derive from the Vistula barges from Thorn (Toruń) that moored here. Previously it was called Knüppelbrücke (Log Bridge). The lane appears on some plans as Thornscher Weg. After the war, this lane was extended to the northwest, beyond Fleischergasse to Wiebenwall. It was intended to form a traffic axis for the Lower Town and the Suburb.
