The Westernfeld brine well was drilled in 1965. The depth of the borehole is 78.5 meters.
The Westernfelder Solequelle was drilled in addition to the old brine spring "Westernkottener Warte", which you can visit in the spa park, in order to secure the brine production in Bad Westernkotten for bathing and health in the long term.
By the way: the original drill head with which the Westernfeld brine spring was drilled at that time can be seen in the Wunderkammer during the usual opening hours of the spa hall.
