Vårby källa, Natural spring in Vårby, Sweden.

Vårby källa is a natural spring near Stockholm that releases mineral-rich water sourced from Uppsalaåsen. The water flows year-round through a dedicated park area at Vårby allé 41 where visitors can access it.

Magnus Oliveblad, owner of Vårby gård, first sought approval for the spring as a health source in 1680. On 31 August 1707 physician Urban Hjärne took water samples, and on 5 May 1709 the spring received a royal privilege as a surbrunn. The cure drew visitors from across Europe for over 40 years, and water was still fetched for the Swedish royal court in the 1840s.

The name Vårby källa refers to the spring at Vårby gård; its water was compared by Urban Hjärne to Medevi brunn. In the 1860s the theatre director Edvard Stjernström rented the brunnshus and held literary lectures there with guests such as Henrik Ibsen and Bjørnstjerne Bjørnson; his widow Louise Granberg-Stjernström continued until 1907.

The spring can be reached via marked paths leading to a maintained park area where water collection is possible. Bring containers if you plan to gather water for your use.

The spring's water was still collected for the Swedish royal court in Stockholm as late as the 1840s, long after the 18th-century spa had faded. In 1935 botanist Rutger Sernander listed Vårby källa as nature monument no. 180 in his register of Stockholm-area sites; it has since lost that status.
