Winzenburg is located in the Leinebergland to the north of Bad Gandersheim, between the national parks of the Harz and the Weserbergland, in Lower Saxony, Germany.

The municipality (German: Gemeinde) was formed on March 1, 1974 from the four previously independent communities of Winzenburg, Schildhorst, Westerberg and Klump.

[2] Klump is below the Sauberg and started out as small farms and farmers who rented the land they lived and worked on.

The village was of greater significance in the 18th and 19th centuries because of Glasfabrik Schildhorst, the glassblowing factory there, which produced white and other glass.

The abundance of water, timber and minerals, natural resources required for the production of glass, made the site particularly suitable.
