Pramen Svoboda, Mineral spring in spa district of Karlovy Vary, Czech Republic

Pramen Svoboda is a mineral spring in the spa district of Karlovy Vary, located in an octagonal wooden pavilion on the left bank of the Teplá River between the Mlynska Colonnade and the Lázne III building. The water source emerges naturally from underground deposits and serves as one of many springs in this renowned spa town.

The spring was first named Lázeňský when it was discovered in 1865 and later took on different names reflecting the political changes of the era. It received its current name in 1946, marking a shift in how the town's water sources were designated.

The spring's name changed with the political regimes: it was called Františka Josefa I. until 1918 and received the name Svoboda, meaning freedom, in 1946. Its water was first piped into the Kurhaus for baths in 1865 and used for the drinking cure from 1872. The octagonal wooden pavilion above the outflow is a replica of the original and is protected as a monument.

The spring is freely accessible at any time in its own pavilion between the Mlýnská Colonnade and the Lázně III building, on the left bank of the Teplá. The water is about 61 to 63 °C, so draw it into a spa cup rather than drinking straight from the outflow. The site lies roughly 400 metres from the Vřídlo outlet.

The water at this spring flows continuously and emerges naturally warm, which distinguishes it from many other sources in the town. Visitors often notice the active bubbling of the water, a defining characteristic that makes the spot memorable.
