Stalpet, Twin waterfall in Aneby, Sweden

Stalpet is a waterfall on the Svartån river in Småland, southern Sweden, where the water falls in two separate cascades over rocky cliff faces into a narrow canyon. The gorge is carved from dark rock and the water moves through a tight corridor before settling into the lower pool.

A watermill was built at the falls in the late 18th century; a weather vane dated 1799 suggests the year. It had two large and two small water wheels driving two millstones, a steel sieve and a barley-groat mechanism. Milling ceased in 1923, when civil engineer Hjalmar Carlsson-Röttle installed a small hydroelectric station. In 1932 Smålands Kraft AB built a new station with a 1,200 hp turbine and a 500-metre tunnel; it is still in operation.

The waterfall sits in a wooded valley near Aneby and draws many visitors in summer who walk along the riverbanks. A seasonal craft shop nearby sells goods made by local artisans, giving the site a grounded, regional feel.

The site is open year-round, and a cafe and parking are available nearby during warmer months. The paths around the gorge can be slippery in wet weather, so sturdy footwear is a good idea.

Aneby Municipality's coat of arms shows a blue topographic waterfall symbol on a stream, a direct reference to Stalpet. The ravine below the falls was cut by meltwater about 12,000 years ago, and Stone Age tools found in it suggest the spot may have served as a cult site.
