The first settlers in the area appear to have been the
Romans, as a Roman column depicting
Jupiter was found buried under a farm along the
Körsch River. The old military roads (Steinernes Kreuz ()) were first built by Roman hands. In AD 600, the first crude iteration of the Church of Saint Martin was constructed here from wood. In the 12th century, one Hugo of Plieningen took the cross and joined the
Fourth Crusade, and the device he chose for himself was three white roses on a field of blue, today Plieningen's coat of arms. Starting in the 12th and 13th centuries, the
House of Plieningen ruled the town from
their nearby castle. The oldest commercial operation of the Plieningens is the Upper Seemühle, which dates back to the 12th century in the Körschtal (). In 1747, the Old Town Hall at Mönchhof was constructed. Later, in 1770,
Duke Charles Eugene of Württemberg constructed Schloss Hohenheim from an old moated castle. On April 1,
1942, Plieningen and
Birkach were accepted into Stuttgart as districts and neighborhoods. When the districts of Stuttgart were divided in
1956, Plieningen was divided into three boroughs: Plieningen, Hohenheim, and Steckfeld. In 2001, all five boroughs of Plieningen were established. ==Attractions==
