Nysø Manor, located near Præstø in the southeast of the Danish island of Sealand, was built in 1673 for Jens Lauridsen, a local functionary.

The first manor house in Denmark to be designed in the Baroque style, it is built in red brick and sandstone with a red-tiled roof and a granite plinth as a foundation.

It is thought to be the work of master builder Ewert Janssen who probably also built Charlottenborg Palace in Copenhagen shortly afterwards.

The central projects on the north and south sides are decorated with four Ionic pilasters which support triangular pediments.

Nysø is especially known for its role in the Danish cultural Golden Age of the early-to-mid-19th century when Baron Henrik Stampe and his wife Christine played host to many famous writers and artists, including Hans Christian Andersen and the sculptor Thorvaldsen.
