The "Royal Mineral Fountain" is located in the capital's "Kniazhevo" district, next to the building of the old bathhouse.
It is called the royal fountain because it was a favorite of Tsar Boris III, who, according to stories, could often be seen walking alone to the spring to pour himself water.
Mineral water helps with neuroses. After use and treatment, insomnia, headache, palpitations, fatigue and stress usually disappear.
