Thune developed in the protection of a castle, which belonged to the Schunterbefestigungen of the 9th / 10th century and first mentioned in 1273 as "castrum thune". After the castle had changed hands several times, it was destroyed in 1492 and 1576 called "desolate". Thune probably got its name from the castle of Thune (1356 "dat slot de Thun", 1388, "thun" = fence). Since 1594 there are first indications of a windmill at the old castle site (1), which was later occupied by a farmyard and a school grounds. Today, on the site of the castle, the equipment house of the volunteer fire department and the kindergarten. Originally Thune was a Rundling, but later developed into a cluster village. Until 1569, the place was eingepfarrt to Bienrode and then belonged to the parish Wenden. In 1754 Thune had about 100 inhabitants, 16 farms and an almost purely peasant population. It was not until the onset of industrialization that the population grew, but increasingly became the basis of the industrial economy, while the peasant share declined. Of the townscape once determining three-way and Hakenhöfen in the village center (2) are now almost all without agricultural use. Today Thune is located on the Mittelland Canal and has an oil port (3). The woodlands near Thune have been a protected landscape area since 1962. In 1974, the village Thune was incorporated to Brunswick.
