The Hot Spring Colonnade (Vřídelní kolonáda) in Karlovy Vary is one of the most remarkable spa structures in the Czech Republic and the most important source of the city’s legendary thermal waters. Built above the powerful Vřídlo geyser, it represents the heart of the entire spa tradition that has made Karlovy Vary famous across Europe for centuries.
The original purpose of the colonnade is closely connected to the natural hot springs that rise from deep underground. The Vřídlo spring is the strongest thermal source in the city, erupting naturally and producing water with a temperature of around 72°C. This unique natural phenomenon has been known since the Middle Ages and has attracted visitors seeking healing treatments, relaxation, and the therapeutic effects of mineral-rich waters.
The current modern structure of the colonnade was built in the 20th century to protect the geyser and provide a functional yet elegant space for visitors. Its glass and concrete design reflects the architectural style of its time, prioritizing practicality and protection of the natural spring while still offering an open and accessible environment. Inside, visitors can directly experience the rising thermal water and observe the geyser’s continuous natural activity.
The Hot Spring Colonnade is not only a technical structure but also a central part of Karlovy Vary’s spa culture. Visitors come here to taste the thermal water using traditional spa cups, continuing a centuries-old wellness tradition. The mineral water is believed to support digestion and overall health, and drinking cures remain an essential part of the spa experience.
Surrounding the colonnade is the elegant spa atmosphere of Karlovy Vary, with nearby promenades, historic buildings, and other famous colonnades such as the Mill Colonnade and Market Colonnade. Together, they form a unique architectural landscape that blends natural healing sources with refined spa architecture.
The Hot Spring Colonnade also plays an important cultural role, symbolizing the connection between nature’s raw power and human effort to preserve and make it accessible. It is one of the most visited and photographed locations in the city.
Today, it remains the living heart of Karlovy Vary’s spa tradition — a place where visitors can witness the strength of nature and experience one of Europe’s most famous thermal springs.
