Limmatquelle — 'Limmat Spring' — is a sulphurous thermal spring associated with the River Limmat that flows through Zurich in Switzerland, connecting the city's geothermal heritage to the broader history of urban thermal bathing. The naturally warm, mineral-rich waters from this source have long been appreciated within a thermal tradition, their sulphurous compounds traditionally associated with the comfort of skin and well-being. The spring represents an intriguing intersection of Swiss urban life and the ancient tradition of seeking relaxation in naturally warm mineral waters.

Insider tip — Limmatquelle is a spring near the Rhine at the Swiss-French-German border triangle where the Limmat and Rhine river systems converge, in an area of significant Roman thermal heritage — the Romans built Aquae Helveticae (Baden) nearby. Though listed under France in this database, the coordinates place this source on the Swiss/German side of the Rhine bend, suggesting it taps the same deep Triassic sandstone aquifer exploited by Baden-Baden to the north. The gently flowing Rhine and surrounding vine-covered hillsides make this border zone distinctly scenic.
