Löchgau was first mentioned in a document dated to between 1105 and 1120 as "Lochenheim". A noble family document as having been influential in the area since the early 12th century sold their share of the village to the Prince-Bishop of Speyer, who turned over the property to Maulbronn Monastery. The Margraviate of Baden made further donations of nearby property to Maulbronn in 1225, as did Rechentshofen Abbey [de] in 1260. In 1416, fully half of Löchgau by the Venningen family to the Margrave of Baden, which was then pledged to the Electoral Palatinates in 1463, to the Duchy of Württemberg in 1504, and then to Baden again in 1529, and then finally and once again to Württemberg in 1595 along with Besigheim. Württemberg acquired the other half of the village from its various owners from 1407 to 1506. The village of Weißenhof was founded 2 kilometers (1.2 mi) south of Löchgau in 1739. In 1810, Löchgau was reassigned from the district of Bietigheim, which was dissolved, to Oberamt Besigheim [de]. This district, too, was dissolved in 1938 and replaced with a new one, Landkreis Ludwigsburg. Löchgau doubled in size in the years after World War II.[2]
Löchgau has one borough (Ortseil), Löchgau, and two villages: Petershöfe and Weißenhof. Löchgau is in a municipal association with Besigheim.[2]
Coat of arms
Löchgau's coat of arms shows a large, yellow "L" next to a six-pointed star of the same color upon a field of blue. The "L" is a local motif that is documented as early as 1684. The star accompanying it first appeared in 1757. This coat of arms was designed based on the suggestions of the Central State Archive Stuttgart [de] in 1921. A corresponding municipal flag was issued by the Ludwigsburg district office on 12 March 1980.[2]
