Less than a half-hour drive (25 kilometers) from Helsingor, near Hillerod, is stunning 17th century Frederiksborg Castle, an absolute must-see if visiting this area.

 Built in the Dutch Renaissance style, Frederiksborg is spectacularly well preserved. The castle lies on three islands in Frederiksborg Lake and was restored in its original style after a fire in 1859. 

Since 1888, the main courtyard has featured a copy of the Fountain of Neptune by Adrian de Vries (1623), the original of which was taken to Sweden in 1658. The Danish Museum of National History has been housed here since 1878.
