History

Numerous remains of early civilization have been found in the area. Tools made of flint and traces of Mesolithic human settlement dated between the 8th and 5th millennium BC were found on several sites on the margins of the Kocher and Jagst valleys. On the Schloßbaufeld plateau (appr. ), situated behind Kocherburg castle near Unterkochen, a hill-top settlement was found, with the core being dated to the Bronze Age. In the Appenwang forest near Wasseralfingen, in Goldshöfe, and in Ebnat, tumuli of the Hallstatt culture were found. In Aalen and Wasseralfingen, gold and silver coins left by the Celts were found. The Celts were responsible for the fortifications in the Schloßbaufeld settlement consisting of sectional embankments and a stone wall. Also, Near Heisenberg (Wasseralfingen), a Celtic nemeton has been identified; however, it is no longer readily apparent. After abandoning the Alb Limes (a limes generally following the ridgeline of the Swabian Jura) around 150 AD, Aalen's territory became part of the Roman Empire, in direct vicinity of the then newly erected Rhaetian Limes. The Romans erected a castrum to house the cavalry unit Ala II Flavia milliaria; its remains are known today as Kastell Aalen ("Aalen Roman fort"). The site is west of today's town centre at the bottom of the Schillerhöhe hill. With about 1,000 horsemen and nearly as many grooms, it was the largest fort of auxiliaries along the Rhaetian Limes. There were Civilian settlements adjacent along the south and the east. Around 260 AD, the Romans gave up the fort as they withdrew their presence in unoccupied Germania back to the Rhine and Danube rivers, and the Alamanni took over the region. Based on 3rd- and 4th-century coins found, the civilian settlement continued to exist for the time being.…

Geography

Aalen is situated on the upper reaches of the river Kocher, at the foot of the Swabian Jura which lies to the south and south-east, and close to the hilly landscapes of the Ellwangen Hills to the north and the Welland to the north-west. The west of Aalen's territory is on the foreland of the eastern Swabian Jura, and the north and north-west is on the Swabian-Franconian Forest, both being part of the Swabian Keuper-Lias Plains. The south-west is part of the Albuch, the east is part of the Härtsfeld, these two both being parts of the Swabian Jura. The Kocher enters the town's territory from Oberkochen to the south, crosses the district of Unterkochen, then enters the town centre, where the Aal flows into it. The Aal is a small river located only within the town's territory. Next, the Kocher crosses the district of Wasseralfingen, then leaves the town for Hüttlingen. Rivers originating near Aalen are the Rems (near Essingen, west of Aalen) and the Jagst (near Unterschneidheim, east of Aalen), both being tributaries of the Neckar, just like the Kocher. The elevation in the centre of the market square is relative to Normalhöhennull. The territory's lowest point is at the Lein river near Rodamsdörfle, the highest point is the Grünberg's peak near Unterkochen at . Aalen's territory ranges over all lithostratigraphic groups of the South German Jurassic: Aalen's south and the Flexner massif are on top of the White Jurassic, the town centre is on the Brown Jurassic, and a part of Wasseralfingen is on the Black Jurassic. As a result, the town advertises itself as a "Geologist's Mecca". Most parts of the territory are on the Opalinuston-Formation (Opalinum Clay Formation) of the Aalenian subdivision of the Jurassic Period, which is named after Aalen. {| class="wikitable…
