Hechingen (Swabian: Hächenga) is a town in central Baden-Württemberg, Germany. It is situated about south of the state capital of Stuttgart and north of Lake Constance and the Swiss border.
The town lies at the foot of the Swabian Alps below Hohenzollern Castle.
The city of Hechingen is subdivided into nine neighborhoods, and the downtown is separated into Oberstadt/Altstadt (Upper Town/Old Town) and Unterstadt (Lower Town).
Other cities in the area include Bodelshausen, Mössingen, Jungingen, Bisingen, Grosselfingen, Rangendingen, and Hirrlingen.
Recent research shows that the battle of Solicinium, fought in 368 between the invading Alamanni and a Roman army led by Emperor Valentinian I, probably took place in the northern part of what is today Hechingen and the lost city Solicinium was located where the Roman museum of Hechingen is located today.
Hechingen is the ancestral home of the Hohenzollern dynasty of princes, electors, kings, and emperors, of Brandenburg, Prussia, the German Empire, and Romania. In 1176 the Counts of Hohenberg separated from the Counts of Hohenzollern and seized several cities from the Hohenzollerns. In 1218 the Burgraves of Nuremberg gained independence from them.
The city was founded in 1255 by the Counts of Hohenzollern as their new capital city. The Hohenzollerns had great land holdings near Strasbourg and in the Alb-Donau-Kreis during this time.
Hechingen was located on an Imperial highway which led from the middle Neckar south by way of Rottweil to the upper Rhine and the Alpine passes. The Counts of Hohenzollern had financial problems and grew steadily weaker. In 1388, there was a siege, following which Eberhard II, Duke of Württemberg gained feudal rights over the territory. The Counts of Hohenzollern became his vassals and opened the town and their castle to him.
After the town was destroyed by fire in 1401, the Count tried to attract new citizens by granting them rights and privileges. The town thus became the center of the county.
