In 1763, King Frederick II of Prussia resided in Dahlen Castle. Here, the Hubertusburger peace pact was ratified.
In 1990/94, the first excavation works and the installation of tensioned ceramic ceilings with provisional boarding began. From 2005 to 2008, the castle was used by a Schloss GbR (private castle), which began security and safety work and started to organise commercial events. Since 2009, the Schloss- und Parkverein Dahlen eV has endeavoured to protect Dahlen Castle from decay.
In the castle park, the oldest tulip tree in Saxony can be seen.
