Gut Neuhof, Manor house estate in Petershagen, Germany.

Gut Neuhof is a manor house with farm buildings in Petershagen that displays typical features of regional estate architecture. The complex consists of the main residence and several outbuildings arranged around a central courtyard.

Gut Neuhof was founded in 1599 by Sophie Klenke, widow of the owner of Schlüsselburg Castle, after inheritance disputes; she merged four noble farms of the castle's outer bailey on the right bank of the Weser. In 1698 the estate passed to Johann Georg Voigt, a Hanoverian district administrator, who had the Baroque buildings rebuilt in the early 18th century. The present two-storey manor house dates from 1748.

The estate's name recalls its founding: in 1599 Sophie Klenke, widow of the owner of Schlüsselburg Castle, merged four noble farms from the castle's outer bailey on the opposite bank into a new court, the "Neuhof". The baroque garden laid out in the 18th century survives in its topography, and a pavilion stands on its Weser side.

Gut Neuhof is private property and only partly open to the public; it now houses a full-time residential facility for people with disabilities, so visitors should keep to the areas that are open. The baroque garden's layout, with its central axis from the entrance and a pavilion on the Weser side, can be seen from the paths.

The baroque garden's original topography survives, and a pavilion stands on its Weser side. The main house and garden follow a central axis starting at the entrance, with the farm buildings flanking it between the drive and the two-storey manor house built in 1748.
