Source Marie-Henriette in Spa, Belgium, is a chloride-bearing mineral spring named after Queen Marie-Henriette of Belgium, who patronised Spa as a therapeutic retreat in the nineteenth century. The spring's saline mineral profile distinguishes it from Spa's more celebrated iron pouhons, adding variety to the town's rich mineral water landscape. Spa's royal connections — the town was a favourite of Peter the Great, Victor Hugo, and numerous European monarchs — are reflected in the spring's regal name, preserving the history of aristocratic spa culture in the Ardennes.
