The Aarewaage (in local Swiss German dialect: Woog) is a whirlpool phenomenon in the Swiss river Aare at Aarburg, canton of Aargau. In 1996, it was added to the Federal Inventory of Landscapes and Natural Monuments. [1]
At the location of the Aarewaage, the river widens into a broader natural basin and at the same time meets a rock on which Aarburg Castle is located. The large whirlpool, the "Waage", is created by the main current of the Aare passing by calmer water in the basin, increasing its water level in cycles, further increased by part of the current being diverted by the castle rock and the influx of the two streams Tych and Dorfbach. [2]
Several times, the existence or appearance of the Aarewaage was threatened by planned construction work. In the 1950s, an expansion of the Ruppoldingen hydroelectric power station that wasn't carried out would have destroyed the basin. In the 1970s, a railway bridge was planned at the Aarewaage, but due to landscape preservation concerns, a tunnel was constructed instead. [3]
In December 2013, a part of the side wall at the Aarewage collapsed. The wall, which itself is a protected monument, was restored from April to May 2014. [4]

The House of Frohburg was a noble family in medieval Switzerland, with possessions in what is now the canton of Solothurn. They originate in the Wigger basin, near Zofingen. In the 10th century, they built Frohburg Castle on a hill near Trimbach. They had the title of counts from the later 11th century. They ruled the lands between Olten and Solothurn, and took parts of Aargau and Sisgau as fief from the bishop of Basel. They reached the peak of their power in the later 12th and early 13th century, building a number of castles, and founding towns such as Aarburg, Liestal, Olten, Waldenburg, Wiedlisbach and Zofingen. They also founded Schöntal Abbey near Waldenburg. The House of Frohburg was divided into three branches, Neu-Homberg, Waldenburg and Zofingen, in c. 1250. The Zofingen branch was extinct in 1307, followed by the Neo-Homberg one in 1325. The Waldenburg branch survived for another 40 years but declined in influence, being forced to sell most of its possessions, most of them to the ascending House of Habsburg. The last count of Frohburg was Hermann VI.
