Frederik II's son, Christian IV was born at Frederiksborg Castle in 1577 and was deeply attached to it. In 1599 he instigated extensive restoration work in the course of which the old main buildings were pulled down and replaced by a magnificent new Renaissance Castle. The Castellan's House and the Chancellery were built on the outer courtyard during the years around 1613. Throughout the seventeenth century, Frederiksborg Castle was often used as a royal residence, but during the succeeding centuries the royal family seldom used it. However, the Castle was of great ceremonial importance. With the introduction of absolutism, Danish kings were no longer crowned but instead anointed in the Chapel at Frederiksborg Castle.
