Forget modern spas for a second. Just over an hour’s drive from Lisbon, a therapeutic “treasure” and world record holder awaits you : the Caldas da Rainha Thermal Hospital. Founded in 1485, it is famous for being a pioneer in Portugal and beyond, but also for the therapeutic qualities of its waters.
A bit of history
Legend has it that one day, on her way to Batalha, Queen Leonor (wife of King João II), troubled by a wound that would not heal, stopped at the site where the thermal building now stands and confirmed the wonders of the hot waters flowing from the springs. In this area, it was common for people to bathe in the waters to alleviate their ailments.
From there, it was only a small step to construction. Between 1484 and 1485, work was carried out on the construction of the world’s oldest thermal hospital; and this is why the therapeutic fame of Caldas da Rainha grew exponentially, remaining to this day a premier thermal destination.
The miracle that springs forth at 34°C
The waters of the Caldas da Rainha Thermal Baths are rich in minerals, notably for their high sulfur content. In general, they are beneficial for treating respiratory, rheumatic, and musculoskeletal conditions. Here, the waters naturally spring forth at around 34°C, making this place a true pilgrimage site for those who need to treat their ailments, but also to relieve stress.
In addition to hydrotherapy services for patients with a doctor’s prescription, the spa also offers a range of options dedicated to care and well-being, such as massages, immersion baths, and Vichy showers. However, visiting this place is about more than just health and relaxation; it’s also synonymous with a getaway rich in architectural and natural heritage.
What you really must visit
Take advantage of your trip to the Caldas da Rainha Thermal Hospital to also explore its museum, where spectacular tile panels stand out , as well as D. Carlos I Park. Located right next to the thermal complex, this park catches the eye of any visitor thanks to its tree-lined avenues and Instagram-worthy artificial lake.
Another place worth visiting is the D. Leonor National Forest, created to protect the springs that supplied the Thermal Hospital. Today, it stands out as a place of great natural beauty, filled with towering trees and 17 hectares of fresh air—perfect for those who enjoy long walks outdoors, especially in the spring.
