Vennerslund is a manor house located 11 km northwest of Nykøbing on the island of Falster in southeastern Denmark.

Frederick II renamed the estate Sophieholm after his wife sin Sophie of Mecklenburg but its old name was reintroduced in 1583.

[1] Christian VII sold the royal holdings on Falster in auction 1766 to make payments on the Danish sovereign debt.

Parcel number seven was acquired by Hans Tersling and Peder Thestrup who constructed a house on the land and named the estate Vennerslund ("Friends' Grove").

A second manor house was built on the land in 1773 after the tenant farmers had complained about the long distances they had to cover to work in the fields.

Ludvig Grandjean founded the stamhus Vennerslund in accordance with his uncle's will from 1840 with the result that it could no longer be sold, pledged or divided between heirs.

Their daughter and only child Susanne Ingeborg Grandjean married on 12 September 1963 to Jens Knud Bille, Count Brockenhuus-Schack, owner of nearby Barritskov.

The current main building is from 1845 and was built by the architect Otto Michael Glahn in the Late Empire style for Ludvig Grandjean.

It is a rectangular, two-storey brick building with white finishing and a median risalit tipped by a triangular pediment on both sides.
