Rittergut Brokeloh, Manor estate in Landesbergen, Germany

Rittergut Brokeloh is a manor estate in Brokeloh, Lower Saxony. Its central building is a four-winged complex: a residential wing with thick masonry walls on the ground floor and a half-timbered upper storey, plus three half-timbered wings enclosing a courtyard of about 15 by 10 metres. A double moat once surrounded the complex.

Clamor von Münchhausen built a moated castle at Brokeloh in 1545, using stones from the family seat at Munichehausen; his son Erich-Hans completed it around 1600. Erich-Hans went bankrupt in 1602 after long lawsuits, including one with Loccum Abbey, and sold the estate. Colonel Otto Plato von Helversen was enfeoffed with it in 1616; it passed by inheritance to the von Roth family, then in 1725 to Colonel Dietrich August von Adelebsen, and in 1734 to Amtmann Christian Eberhard Niemeyer, whose descendants still own it.

Since 2004 the estate has hosted Conquest of Mythodea, a live role-playing event held each year on 60 hectares around the manor, drawing up to 8,000 fantasy fans from Europe and beyond. The Niemeyer family, owners since 1734, still farms the property; Carsten Niemeyer took over management in 1986.

The estate lies in Brokeloh, not Landesbergen, in the moorland of Lower Saxony. The four-winged house with its half-timbered upper storey and three timber-framed wings encloses a courtyard of about 15 by 10 metres; a double moat once surrounded the complex. The grounds are private and farmed by the Niemeyer family, so visits should be arranged in advance.

Since 2004 the estate's 60 hectares have hosted Conquest of Mythodea, a live-action role-playing event that draws up to 8,000 fantasy players from Europe and beyond each year. The fields around the manor briefly become a fictional world of camps and costumes.
