Bernstorff Castle in Gentofte was built in 1765, and was originally a summer house for the foreign minister of the time Johan Hartvig Ernst Bernstorff.
The castle has been open as a hotel and conference center since 2009, so today everybody can enjoy the castle.
Besides being a hotel, the castle also offers a brunch buffet and guided tours. It is necessary to book a table beforehand, and guided tours are only on selected dates.
