Pouhon Pierre le Grand
The best-known of Spa’s water sources—locally known as pouhons—is the Pouhon Pierre Le Grand, which can be visited by tourists as well as curistes (people taking the cure). In past times, pregnant women came to drink the iron-rich water. Nowadays, the source draws those with poor circulation, anemia, and arthritis. The building housing the spring dates from 1880, although is was given a major face-lift in 2012.
