The theories about the location of the Battle of the Teutoburg Forest have emerged in large numbers especially since the beginning of the 16th century, when the Tacitus works Germania and Annales were rediscovered.
The assumptions about the possible place of the battle are based essentially on place names and river names, as well as on the description of the topography by the ancient writers, on investigations of the prehistoric road network, and on archaeological finds.
Only a few assumptions are scientifically based theories.

The prehistorian and provincial archaeologist Harald Petrikovits combined the several hundred theories in 1966 into four units:
according to the northern theory on the northern edge of the Wiehen Hills and Weser Hills
according to Lippe theory in the eastern half of the Teutoburg Forest or between this and the Weser river
according to the Münsterland theory south of the Teutoburg Forest near Beckum or just to the east of it and
according to the southern theory in the hill country southeast of the Westphalian Lowland.

For almost 2,000 years, the site of the battle was unidentified.
The main clue to its location was an allusion to the saltus Teutoburgiensis in section i.60–62 of Tacitus' Annals, an area "not far" from the land between the upper reaches of the Lippe and Ems rivers in central Westphalia.
During the 19th century, theories as to the site abounded, and the followers of one theory successfully argued for a long wooded ridge called the Osning, near Bielefeld.
This was then renamed the Teutoburg Forest.

Late 20th-century research and excavations were sparked by finds by a British amateur archaeologist, Major Tony Clunn, who was casually prospecting at Kalkriese Hill (52°26′29″N 8°08′26″E) with a metal detector in the hope of finding "the odd Roman coin".
He discovered coins from the reign of Augustus (and none later), and some ovoid leaden Roman sling bolts.
Kalkriese is a village administratively part of the city of Bramsche, on the north slope fringes of the Wiehen, a ridge-like range of hills in Lower Saxony north of Osnabrück.
This site, some 100 km north west of Osning, was first suggested by the 19th-century historian Theodor Mommsen, renowned for his fundamental work on Roman history.

Initial systematic excavations were carried out by the archaeological team of the Kulturhistorisches Museum Osnabrück under the direction of Professor Wolfgang Schlüter from 1987.
Once the dimensions of the project had become apparent, a foundation was created to organise future excavations and to build and operate a museum on the site, and to centralise publicity and documentation.
Since 1990 the excavations have been directed by Susanne Wilbers-Rost.

Excavations have revealed battle debris along a corridor almost 24 km (15 miles) from east to west and little more than a mile wide.
A long zig-zagging wall of peat turves and packed sand had apparently been constructed beforehand: concentrations of battle debris in front of it and a dearth behind it testify to the Romans' inability to breach the Germans' strong defence.
Human remains appear to corroborate Tacitus' account of the Roman legionaries' later burial.
Coins minted with the countermark VAR, distributed by Varus, also support the identification of the site.
As a result, Kalkriese is now perceived to be an event of the Battle of the Teutoburg Forest.

The Varusschlacht Museum und Park Kalkriese includes a large outdoor area with trails leading to a re-creation of part of the earthen wall from the battle and other outdoor exhibits.
An observation tower, which holds most of the indoor exhibits, allows visitors to get an overview of the battle site.
A second building includes the ticket centre, museum store and a restaurant.
The museum houses a large number of artefacts found at the site, including fragments of studded sandals legionaries lost, spearheads, and a Roman officer's ceremonial face-mask, which was originally silver-plated.
