Rommelmühle, Watermill in Bietigheim-Bissingen, Germany.

Rommelmühle is a former watermill on the Enz in Bietigheim-Bissingen, its seven-storey main building with a listed clinker brick facade still shaping the Bissingen townscape. Inside, flats are arranged as lofts over two levels, and the riverside area now holds a beer garden.

The mill was documented as early as 1325 and was rebuilt after a fire in 1903 following its purchase by Karl Rommel in 1854. These events shaped the building as it stands today.

The name Rommelmühle comes from Karl Rommel, who bought the mill in 1854 and rebuilt it after the 1903 fire. Today a beer garden sits by the renaturalised Enz, and the former mill channels still house turbines. The site also holds a bio-supermarket and a restaurant, so visitors encounter a working mix of energy production, shopping and riverside dining.

The beer garden sits in the renaturalised bank area of the Enz, next to the preserved weir and reservoir. The other structures, including the carports, were built in the direction of the river's flow so they would not raise water levels during floods. The former mill building now holds flats, offices and a bio-supermarket alongside the restaurant.

Four turbines run in the former mill channels beneath the building, feeding electricity into the power grid while using waste heat to warm the structure. This approach connects historical water power with modern energy generation.
