Aalen is a former Free Imperial City located in the eastern part of the German state of Baden-Württemberg, about 70 kilometres (43 mi) east of Stuttgart and 48 kilometres (30 mi) north of Ulm. It is the seat of the Ostalbkreis district and is its largest town. It is also the largest town in the Ostwürttemberg region. Since 1956, Aalen has had the status of Große Kreisstadt (major district town). It is noted for its many half-timbered houses constructed from the 16th century through the 18th century.
With an area of
146.63 km2, Aalen is ranked 7th in Baden-Württemberg and 2nd within the
Government Region of Stuttgart, after Stuttgart. With a population of about
66,000, Aalen is the 15th most-populated settlement in Baden-Württemberg.
Situation
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 430 metres (1,410 ft) 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 733
metres (2,405 ft).
Geology
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, which is named after Aalen. On the Sandberg, the
Schnaitberg and the Schradenberg hills, all in the west of Aalen, the
Eisensandstein (Iron Sandstone) formation emerges to the surface. On the other
hills of the city, sands (Goldshöfer Sande), gravel and residual rubble
prevail. The historic centre of Aalen and the other areas in the Kocher valley
are founded completely on holocenic floodplain loam (Auelehm) and riverbed
gravel that have filled in the valley.
Most parts of
Dewangen and Fachsenfeld are founded on formations of Jurensismergel (Jurensis
Marl), Posidonienschiefer (cf. Posidonia Shale), Amaltheenton (Amalthean Clay),
Numismalismergel (Numismalis Marl) and Obtususton (Obtusus Clay, named after
Asteroceras obtusum ammonites) moving from south to north, all belonging to the
Jurassic and being rich in fossils. They are at last followed by the Trossingen
Formation already belonging to the Late Triassic.
Until 1939 iron
ore was mined on the Braunenberg hill.
Extent of the
borough
The maximum
extent of the town's territory amounts to 18 kilometres (11 mi) in a
north-south dimension and 25 kilometres (16 mi) in an east-west dimension. The
area is 14,662.8 hectares (36,233 acres), which includes 42.2% 6,186.2 hectares
(15,286 acres) agriculturally used area and 37.7% 5,534.9 hectares (13,677
acres) of forest. 11.5% 1,692.3 hectares (4,182 acres) are built up or vacant,
6.4% 932.8 hectares (2,305 acres) is used by traffic infrastructure. Sporting
and recreation grounds and parks comprise 1% 152.7 hectares (377 acres), other
areas 1.1% 163.9 hectares (405 acres).

Boroughs
Aalen's territory
consists of the town centre (Kernstadt) and the municipalities merged from
between 1938 (Unterrombach) and 1975 (Wasseralfingen, see mergings section).
The municipalities merged in the course of the latest municipal reform of the
1970s are also called Stadtbezirke (quarters or districts), and are Ortschaften
("settlements") in terms of Baden-Württemberg's Gemeindeordnung
(municipal code), which means, each of them has its own council elected by its
respective residents (Ortschaftsrat) and is presided by a spokesperson
(Ortsvorsteher).
The town centre
itself and the merged former municipalities consist of numerous villages
(Teilorte), mostly separated by open ground from each other and having their
own independent and long-standing history. Some however have been created as
planned communities, which were given proper names, but no well-defined
borders.
Spatial planning
Aalen forms a
Mittelzentrum ("medium-level centre") within the Ostwürttemberg
region. Its designated catchment area includes the following municipalities of
the central and eastern Ostalbkreis district: Abtsgmünd, Bopfingen, Essingen,
Hüttlingen, Kirchheim am Ries, Lauchheim, Neresheim, Oberkochen, Riesbürg and
Westhausen, and is interwoven with the catchment area of Nördlingen, situated
in Bavaria, 30 kilometres (19 mi) east of Aalen.
Climate
As Aalen's
territory sprawls on escarpments of the Swabian Jura, on the Albuch and the
Härtsfeld landscapes, and its elevation has a range of 355 metres (1,165 ft),
the climate varies from district to district.
The weather station
the following data originate from is located between the town centre and
Wasseralfingen at about 48°51′02″N 10°05′44″E and has been in operation since
1991.
The sunshine
duration is about 1800 hours per year, which averages 4.93 hours per day. So
Aalen is above the German average of 1550 hours per year. However, with 167
days of precipitation, Aalen's region also ranks above the German average of
138. The annual rainfall is 807 millimetres (31.8 in), which places Aalen in
the middle within Baden-Württemberg. The annual mean temperature is 9.9 °C
(49.8 °F). Here Aalen ranks above the German average of 8.2 °C (46.8 °F) and
the Baden-Württemberg average of 8.1 °C (46.6 °F).
History
Civic history
First settlements
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. 650 by 350 metres (2,130 by 1,150 ft)),
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.
Roman era
After abandoning
the Alblimes (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 greatest 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. However, there is no
evidence of continued civilization between the Roman era and the Middle Ages.
Foundation
Based on
discovery of alamannic graves, archaeologists have established the 7th century
as the origination of Aalen. In the northern and western walls of St. John's
church, which is located directly adjacent to the eastern gate of the Roman
fort, Roman stones were incorporated. The building that exists today probably
dates to the 9th century.
The first mention
of Aalen was in 839, when emperor Louis the Pious reportedly permitted the
Fulda monastery to exchange land with the Hammerstadt village, then known as
Hamarstat. Aalen itself was first mentioned in an inventory list of Ellwangen
Abbey, dated ca. 1136, as the village Alon, along with a lower nobleman named
Conrad of Aalen. This nobleman probably had his ancestral castle at a site
south of today's town centre and was subject first to Ellwangen abbey, later to
the House of Hohenstaufen, and eventually to the House of Oettingen. 1426 was
the last time a member of that house was mentioned in connection with Aalen.
Documents, from the Middle Ages, indicate that the town of Aalen was founded by
the Hohenstaufen some time between 1241 and 1246, but at a different location
than the earlier village, which was supposedly destroyed in 1388 during the war
between the Alliance of Swabian Cities and the Dukes of Bavaria. Later, it is documented
that the counts of Oettingen ruled the town in 1340. They are reported to have
pawned the town to Count Eberhard II and subsequently to the House of
Württemberg in 1358 or 1359 in exchange for an amount of money.
