Frederiksborg Castle is one of my favorite castles in Denmark. The location, the castle itself and the gardens are simply spectacular.
Frederiksborg Castle is situated in the centre of Hillerod on three islets in the Castle Lake surrounded by Frederiksborg Castle Gardens.
Frederiksborg Castle Gardens consist of a romantic landscaped garden and a baroque garden, recreated in 1996 according to studies of J.C. Krieger's gardens from 1725. (Source)
