When the monarch is in residence, the King's Guard (Kongevagt) also march alongside the changing of the guard at noon, accompanied by a band that plays traditional military marches. The Guard Lieutenant (Løjtnantsvagt) is always alerted when Prince Henrik or another member of the royal family are reigning in absence of the Queen. There are three types of watches: King's Watch, Lieutenant Watch and Palace Watch. A King's Watch is when Her Majesty the Queen takes up residence in Christian IX's Palace. A Lieutenant Watch is when Crown Prince Frederik, Prince Joachim, or Princess Benedikte, takes the place as regent, when the monarch is unable to. A Palace Watch is when no member of the royal family is in the palace, and it is the smallest one. [4]
