Frederiksborg Castle, housing the Museum of National History, is a magnificent Renaissance castle in Hillerød, Denmark, easily accessible by public transport from Copenhagen. Visitors can explore independently, often with audio guides available, or join a guided tour for deeper insights; while most main areas are accessible, some older parts may have stairs. The castle is open year-round, but the grand Baroque Garden is particularly stunning in spring and summer. A typical visit, including the museum, chapel, and gardens, usually lasts between 2 to 4 hours. Entrance fees are standard for a major European attraction, generally ranging from 75-100 DKK or more depending on current exhibitions, making it a moderately priced experience offering rich cultural and historical value.
