What is "lustschloss"

In Renaissance and Early Modern German architecture, a Lustschloss is a small palace which served the private pleasure of its owner, usually the ruler of the area it is located in, and was seasonally inhabited as a respite from court ceremonies and state duties. In France, the château de Madrid in the Bois de Boulogne, easily reached from Paris, set an example, and Louis XIV similarly retreated from onerous ceremonial at Versailles to his château of Marly.

Lustschloss is often loosely used interchangeably with Jagdschloss, for both served as non-formal residences, but a Jagdschloss was a hunting retreat and was usually used to host a ruler and his hunting party.
