Origin of the name Löwenbourg

The German name Löwenburg means « castle of the lion ». It is not known why it was chosen. Around 1200 the lords of Löwenberg, from the Sundgau, introduce a lion into their coat of arms.[1]

Founding of Löwenbourg

The Löwenbourg, in the municipality of Pleigne, owes its first occupation to its Kimmeridgian limestone bedrock, which contains flint, worked as early as the Mousterian by Neanderthals, then in the Epipalaeolithic, Mesolithic and Neolithic. The castle dates back to the 10th century. It is not known who built it. Built of wood, it was rebuilt in stone shortly before 1200, passed to the count of Ferrette in the mid-13th century, then to the Habsburgs in the 14th century. In 1526 the Basel family Münch had to cede it to Lucelle Abbey. The monks abandoned the castle in favour of a converted and fortified farm, the « franche courtine », which forms the present estate.[1][2][3]
