Hennef

Hennef is an administrative municipality in Rhein-Sieg District, Germany, located along the River Sieg. The municipal area comprises numerous districts and formerly independent communities that now form the town together.

The first mention of Hennef dates back to 885, while the medieval fortification Stadt Blankenberg was built around 1180. Parts of this old fortress remain preserved to this day.

St Catherine's Church displays wall paintings from the 1200s and 1300s, while the Tower Museum opens during warmer months to present local heritage. Visitors can see how life along the Sieg developed through the centuries.

The town maintains direct rail connections to Cologne and Bonn, with the main station located roughly 29 kilometers from Cologne and 14 kilometers from Bonn. The numerous districts are linked through a network of roads and public transport.

In 1883, residents Carl Reuther and Eduard Reisert invented an automatic balance scale, commemorated through a 22-stop Weigher Walking Way around town. This walking route tells the story of the local invention and its importance for the development of weighing technology.
