Wetter (Ruhr) is a historic town in the Ennepe-Ruhr district, profoundly shaped by its pivotal role in the early industrial age. Located along the northern slopes of the Ruhr valley, the town overlooks Lake Harkortsee, a large reservoir created for industrial and recreational purposes. It is famously known as the home of Friedrich Harkort, a pioneer of the German machine industry who established his workshops in the ruins of Wetter Castle in 1819. The 'Burgfreiheit' area remains a testament to its medieval past, featuring pleasant timber-framed and slate-clad buildings that once housed the counts of the Mark. Today, Wetter is a global player in the security industry, hosting the headquarters of ABUS, a world leader in locks and safety equipment. The town serves as a green oasis within the metropolitan region, offering residents and visitors access to the Ruhr Valley Cycle Path and various nautical activities on the lake. Its hilly terrain provides numerous vantage points with panoramic views of the river landscape and the nearby Sauerland hills.
