Malfoy Manor is the home of the aristocratic Malfoy family: Lucius, Narcissa, and Draco Malfoy, and later Bellatrix Lestrange (sister of Narcissa). It is mentioned in the fifth book that the manor is located somewhere in Wiltshire, England. The Malfoys were previously served by Dobby the house elf, before Lucius was tricked by Harry into freeing him.
Voldemort used Malfoy Manor as headquarters on at least one occasion in Deathly Hallows. The three Malfoys seemed quite displeased by this use of their manor as Voldemort himself noted; only Bellatrix appears to be pleased he is there. The Malfoys have become prisoners in their own home and in very real fear for their lives. During the Deathly Hallows novel, several prisoners are being kept in the basement on Voldemort's orders, including Luna Lovegood, Dean Thomas, Griphook the Goblin, and Mr Ollivander. When Snatchers capture Harry, Ron, and Hermione, they are brought to Malfoy Manor. They escape with the other prisoners thanks to Dobby's help. The four residents of the manor are then placed under house arrest by Lord Voldemort, until they join with other Death Eaters in the Battle of Hogwarts.
Malfoy Manor was inspired by and partly shot at Hardwick Hall, Derbyshire – a National Trust property.
