The Palace of Holyroodhouse (/ˈhɒlɪˌruːd/ or /ˈhoʊlɪˌruːd/), commonly referred to as Holyrood Palace or Holyroodhouse, is the official residence of the British monarch in Scotland. Located at the bottom of the Royal Mile in Edinburgh, at the opposite end to Edinburgh Castle, Holyroodhouse has served as the principal royal residence in Scotland since the 16th century, and is a setting for state occasions and official entertaining. The late Queen Elizabeth II spent one week in residence at Holyroodhouse at the beginning of each summer, where she carried out a range of official engagements and ceremonies. The 16th-century historic apartments of Mary, Queen of Scots, and the State Apartments, used for official and state entertaining, are open to the public throughout the year, except when members of the royal family are in residence. The Queen's Gallery was built at the western entrance to the Palace of Holyroodhouse and opened in 2002 to exhibit works of art from the Royal Collection. The gardens of the palace are set within Holyrood Park.
