Blenheim Palace is a monumental country house situated in Woodstock and is the residence of the dukes of Marlborough. It is the only non-royal non-episcopal country house in England to hold the title of palace.
Designed in the rare, and short-lived, English Baroque style the palace was built between 1705 - 1722 and was designated a UNESCO World Heritage Site in 1987.
Its construction was originally intended to be a gift to John Churchill, 1st Duke of Marlborough, from a grateful nation in return for military triumph against the French and Bavarians at the Battle of Blenheim. However, it soon became the subject of political infighting, which led to Marlborough's exile, the fall from power of his duchess, and irreparable damage to the reputation of the architect Sir John Vanbrugh.
Following the palace's completion, it became the home of the Churchill family for the next 300 years, and various members of the family have in that period wrought various changes, in the interiors, park and gardens. At the end of the 19th century, the palace was saved from ruin by funds gained from the 9th Duke of Marlborough's marriage to American railroad heiress Consuelo Vanderbilt.
The palace is also notable as the birthplace and ancestral home of Sir Winston Churchill.
