English: coat of arms of Ahrbergen, Giesen, Lower Saxony, Germany

English: The coat of arms represents the history and location of the village with rich symbolism. Just as the broad wavy line splits the coat of arms, so too does the Innerste River cut Ahrbergen's fields into two parts. On the left side of the river, the church stands on a small, artificially created elevation. According to the chronicle, it was built on the site of an old castle. Its tower was erected in 1236 by Bishop Konrad II as a fortification tower and is the oldest preserved building in Ahrbergen. Therefore, the left half of the coat of arms shows this memorable tower. The elevated ground is green like sprouting crops; the tower is golden, and the background is red. The right side honors the memory of the noble free family of Depenau. They owned estates in Algermissen, Giesen, and Hotteln, among others, and also possessed large landholdings in Ahrbergen. Hence, around 1175, one of their descendants, named Cuno or Cono, called himself Lord of Ahrbergen. The family line died out in 1286. Whether the Lords of Ahrbergen, who appear as citizens in Hildesheim in the 14th century, are related to them is doubtful. The Depenau family had a horizontal bar in their coat of arms, which was charged with three iron hats. The same heraldic image is shown today in the right half of Ahrbergen's shield. The background is golden, the horizontal bar is red, and the iron hats are silver-colored. The Depenau coat of arms on the right side of the shield reminds us of the time and customs of the forefathers, the church tower of piety and virtue, the line that halves the shield of the home river, and the colors of the homeland.
