Frederiksborg Castle in Hillerød (Hilleroed or Hillerod) near Copenhagen in Denmark. The castle is built in Dutch Renaissance style and is located in the middle of Hilleroed on three islands in the castle lake. The oldest parts of the castle were built in 1560 by King Frederik the 2nd and the castle is named after him.
The majority of the present castle was built between 1600-1620 by Frederik II's son, Christian IV in Dutch Renaissance style with sweeping gables, sandstone decorations and copper-covered roofs and spires. The castle burnt in 1859 but was rebuilt from 1860-84 with financial support from brewer J. C. Jacobsen and later by the Carlsberg Foundation.
