Leeds Castle is a castle in Kent, England, 5 miles (8 km) southeast of Maidstone. It is built on islands in a lake formed by the River Len to the east of the village of Leeds.
From 857 the site was owned by a Saxon chief called Led or Leed who built a wooden structure on two islands in the middle of the River Len. In 1119 Robert de Crevecoeur rebuilt it in stone as a Norman stronghold and Leeds Castle descended through the de Crevecoeur family until the 1260s. What form this Norman stronghold took is uncertain because it was rebuilt and transformed in the following centuries. Adrian Pettifer speculates that it may have been a motte and bailey.
In the 13th century it came into the hands of King Edward I, for whom it became a favourite residence; in the 16th century, Henry VIII used it as a dwelling for his first wife, Catherine of Aragon.
The present castle dates mostly from the 19th century. Robert Fairfax owned the castle for 46 years until 1793 when it passed to the Wykeham Martins. Sale of the family estates in Virginia released a large sum of money that allowed extensive repair and the remodelling of the castle in a Tudor style, completed in 1823, that resulted in the appearance today.
The castle also hosted the Northern Ireland peace talks held in September 2004 led by Tony Blair.
