Lüneburg is a town in northern Germany. In the medieval old town, red Brick Gothic–style buildings frame Am Sande square. Housed in the former Lüneburg Saltworks, the German Salt Museum details the history and importance of salt mining, the source of the city's medieval wealth. Many buildings in the historic quarter lean due to centuries of mining. Lüneburg Kalkberg, a limestone hill, sits in a nearby nature reserve.

The first signs of human presence in the area of Lüneburg date back to the time of Neanderthal Man: 56 axes were uncovered during the construction in the 1990s of the autobahn between Ochtmissen and Bardowick. The site of the discovery at Ochtmissen was probably a Neanderthal hunting location where huntsmen skinned and cut up the animals they had caught.

The area was almost certainly not continuously inhabited at that time, however, due to the various glaciations. The first indication of a permanent, settled farming culture in the area was found not far from the site of the Neanderthal discovery in the river Ilmenau between Lüne and Bardowick. This was an axe that is described as a Schuhleistenkeil or "shoe last wedge" due to its shape. It dates to the 6th century BC and is now in the collection of the Lüneburg Museum.

Since the Bronze Age, the Lüneburg hill known as the Zeltberg has concealed a whole range of prehistoric and early historic graves, which were laid out by people living in the area of the present-day town of Lüneburg. One of the oldest finds from this site is a so-called Unetice flanged axe (Aunjetitzer Randleistenbeil) which dates to 1900 BC.

The land within the town itself has also yielded a number of ice age urns that were already being reported in the 18th century. These discoveries are, however, like those from the Lüneburger Kalkberg — they went into the private collections of several 18th century scholars and, with a few exceptions, were lost when the scholars died.

Also worth mentioning in this regard are the Lombard Urnfield graves on the Lüneburg Zeltberg and Oedeme from the first few centuries AD. In the Middle Ages, there several discoveries were made on the site of the town, for example on the site of the old village of Modestorpe not far from St. John's Church (Johanniskirche), at the Lambertiplatz near the saltworks and in the old Waterside Quarter.

The ancient town may be that identified as Leufana or Leuphana, a town listed in Ptolemy in the north of Germany on the west of the Elbe.

The Lüneburg Theatre (Theater Lüneburg) is one of the smallest, three-stage theatres in Germany. Not only are plays of all styles put on, but also operas, operettas, musicals and ballets. Although the financial means of the Lüneburg Theatre are comparatively limited, it is no 'provincial stage' and can hold its ground successfully against the many theatres in nearby Hamburg. In addition Lüneburg has a large number of amateur theatres, that also produce regular performances. Such a variety in amateur drama is otherwise only found in large cities like Hamburg or Hanover.

The historic town is itself a kind of open-air museum (a "Rothenburg of the North"), but there are numerous museums and historic churches (St. Michaelis, St. Johannis, St. Nicolai. The most important museums are the German Salt Museum in the premises of the old Lüneburg Saltworks, in which the significance of salt in the Middle Ages and the extraction of salt is portrayed, and the Museum of the Principality of Lüneburg, in which the town's history and the history of the surrounding area is captured. Also worthy of mention are the East Prussian Regional Museum, the nearby North German Brewery Museum with a gallery of valuable drinking vessels (over 1200 years), the 1485 Kronen Brewery of Lüneburg and the Lüneburg Nature Museum on the edge of the subsidence zone.

Lüneburg is one of the few towns in North Germany whose historic centre was not destroyed during the Second World War. Nevertheless, the general neglect of its buildings until the 1960s and the damage in the area of subsidence has led to gaps in the historic architecture of the town. In addition the demolition of ramshackle buildings in the 1950s and 1960s and the construction of shops with a contemporary design broke up the historic appearance of many rows of houses. Since the beginning of the 1970s, however, Lüneburg has been carefully restored. The restoration process revealed hitherto hidden ceiling frescos, medieval pottery workshops and many historic soakaways (Sickergruben) from which a considerably better picture of life in the Middle Ages resulted.

In the Lüneburg Stadtteil of Kaltenmoor is St. Stephen's (St. Stephanus), the oldest ecumenical building in the town, with Protestant and Catholic churches under one roof. Other buildings worthy of mention are the three remaining town churches: St. Johannis am Sande (completed 1370), St. Michaelis where Johann Sebastian Bach was a choirboy from 1700 to 1702, and the relatively 'modern' St. Nicolai which was built in 1407. The Church of St. Lambertus (St. Lamberti) was demolished in 1850 due to its dilapidated state; it stood in the subsidence area.

In addition there are the Glockenhaus ("Bell House", an old armoury) on the Glockenhof, the Rathsapotheke (town chemist's), dating to 1598, in Große Bäckerstraße and the historic town hall or Rathaus with its famous town council meeting room, the Gerichtslaube. The Luna Fountain (Lunabrunnen) in front of the town hall is graced by a bronze statue of the moon goddess with bow and arrow; the original dating to 1532 was stolen in 1970 and melted down; the present statue is a replica dating to 1972. In the area of the old port can still be seen the Baroque façade of the "Old Store" (Altes Kaufhaus), most of the rest of which was burned down and had to be replaced by one that was more suitable for a fire station. The port is also home to the "Old Crane" (Alter Kran), a wooden, medieval riverside crane that is still in working order today and which has two large wheels inside that enable the crane cable to be raised and lowered. The fire station moved in autumn 2007 to a new building on the edge of the town centre; the Altes Kaufhaus has since (2009) been converted into a hotel.

On the southern edge of the town centre is the Lüneburg Water Tower which now acts as an observation tower.

In front of the gates of the old town is Lüne Abbey, a former Benedictine nunnery. It was built in 1172 and has been restored.

About 2 kilometres (1 mile) west of Lüneburg, in the villages of Reppenstedt and Vögelsen, is a well-preserved section of the historic Lüneburg Landwehr, a boundary embankment and ditch, that can be walked.
