In 1722, Potter's fire engine was built in the Althandel shaft – a unique work of European importance. Isaac Potter built it specifically for the town of Nová Baňa and used steam power for the first time on the European continent. The machine was used to drain water from flooded mines. With each stroke, the machine drained 1 bucket of water (50 l) and made 14 strokes per minute. The foundations of this important technical work were discovered in 2019 and research is still ongoing. The plan is also to build a replica of the machine and the museum. Moving miniature model of the machine is displayed in the Pohronské Museum.
