Burghley House was built by William Cecil, later Lord Burghley, Elizabeth I's Secretary of State and closest adviser. It was originally designed in the shape of an 'E' to honour the queen, although she was never to visit. However, Queen Victoria was one of many high-profile visitors to the house and she planted a tree in the family's personal gardens at the back of the house. The gardens and park of Burghley House were laid out by Lancelot 'Capability' Brown in the 18th century, in line with many great houses of the time.
William Cecil's descendants still live in the house and hold the Burghley Horse Trials every September, which have been running since 1961.
