On the pasture, 6 km from Kanjiža, in 1907 there were two artesian wells for watering livestock. Given the increased needs, shepherds turned to the city authorities with a request to drill two more wells.
Already in May 1908, a new well was drilled. The water from that well had a yellowish color, and flammable gas came out of the pipes. Such characteristics were enough for various legends to arise about the medicinal properties of the well. Very quickly, the people named the well the "Miracle Well".
A story is connected to the miracle well about a Roma woman who cured her aching joints by bathing in this water. The city fathers reacted quickly and logically, and already in 1908, they opened the "First Season" of bathing in the water of the miracle well. Bathing was already charged back then. The excellent business sense of those people is also proven by the fact that already in 1909, based on the decision of the City Assembly, water samples were sent for testing to the Royal Institute of Chemistry in Budapest.
Analyses were completed in 1910. Already in 1909, a businessman from Kanjiža, Herman Grünfeld (director of the then brickyard), insisted on forming a joint-stock company to open a spa. The city authorities gave their consent, and the Joint-Stock Company was formed, headed by Mr. Herman Grünfeld.
In July 1912, projects for the new spa were completed, and on August 10, 1913, the new artesian bath of the miracle well in Old Kanjiža was officially opened. The new building had 12 rooms and 20 tubs. The building had steam heating and electric lighting. For years, the water was bottled in dark green bottles under the name "Water of the Miracle Well - Old Kanjiža".
From 1945 to 1953, the Spa operated as a state institution called the "Artesian Bath". On June 24, 1976, the Spa separated from the Kanjiža Health Center by referendum and has since operated under the name Center for Rehabilitation and Recreation "Banja" in Kanjiža.
