Rittergut Großgoltern, Manor estate in Barsinghausen, Germany.

Rittergut Großgoltern is a manor estate in Barsinghausen featuring a main residence surrounded by a water-filled moat approximately 6 meters wide with two side wings attached. A gatehouse connects these structures to agricultural buildings, creating an integrated complex of residential and working spaces.

The estate's origins reach back to the Middle Ages and the von Goltern family; it may have existed when Großgoltern was first mentioned in 1158. After that family died out, Duke Erich II of Brunswick-Lüneburg granted it in 1558 to cavalry captain Ernst von Alten, whose family has held it since. The central tract of the manor house dates to the 17th century, and in 1886 Hanover architect Hermann Schaedtler replaced the north wing with a new building in the older style.

The estate has belonged to the von Alten family since 1558, when Duke Erich II of Brunswick-Lüneburg granted it to cavalry captain Ernst von Alten after the von Goltern line died out. Five grave slabs are set into the courtyard walls of the manor house, the oldest dated 1492, and an 800-metre chestnut avenue leads from the open west side to the family burial ground in the fields.

The estate is located on Gutsstraße 8 and welcomes visitors who should check in advance about available days for tours or events. It is best accessed by car or on foot, with parking likely available near the main entrance.

A striking chestnut tree avenue extends approximately 800 meters from the manor house to the von Alten family burial ground in the surrounding countryside. This tree-lined passage created a physical connection between the residence and the family's commemorative site.
